What is more important than an ecg or an ultrasound of the heart? What is better to do an ECG or ultrasound of the heart and what is the difference between these procedures? Changes that are detected by ECG

In cardiology there are no unnecessary or useless diagnostic studies. For each technique there are indications that allow you to assess the condition of the heart muscle. It is impossible to say which is better - a cardiogram or an ultrasound of the heart: one technique is very different from the other, so there is no need to even try to identify one optimal method for diagnosing pathology of cardio-vascular system. In each case and for each patient, the doctor will use specific set diagnostics, most suitable for the effective detection of cardiac pathology.

Cardiogram: indications for conducting

Recording an electrocardiogram is necessary in the following cases:

  • chest pain on the left, even if the problem occurs occasionally;
  • acute sudden pain syndrome on the left side of the chest, especially if the pain radiates to left hand or spatula;
  • high blood pressure;
  • pulse rhythm disturbance;
  • constant or intermittent pressing sensations in the chest or upper abdomen;
  • at the stage of preparation for any surgical interventions;
  • control of treatment of angina pectoris and myocardial infarction;
  • for preventive purposes in all people once every 3 years (dispensary examination).

Essentially, ECG is effective and simple method detection of heart disease during mass medical examinations, preparation for surgical interventions, constant monitoring of the effectiveness of conservative treatment of diseases of the cardiovascular system. IN emergency situations A person’s life depends on the speed of recording a cardiogram.

Ultrasound of the heart: indications

An undoubted advantage ultrasound examination in comparison with other methods, it is possible to detect pathological changes in the myocardium. A cardiogram is unable to detect a severe heart defect, but an ultrasound will show the doctor serious anatomical problems of the cardiovascular system.

Ultrasound of the heart must be done in the following cases:

  • in children with suspected congenital anomalies development;
  • in adults to detect rheumatic or other acquired defects;
  • when symptoms of an infectious lesion of the heart cavities appear;
  • to identify post-infarction changes in the heart muscle;
  • for timely detection of aneurysms;
  • with intracardiac thrombosis;
  • with tumor formations in the breast;
  • to monitor the condition of the heart in the postoperative period.

Ultrasound of the heart is best performed in situations where there is a high risk anatomical changes in the internal cavities and external cardiac sac. Good effect may give an ultrasound to evaluate the function of the heart valves. Important information will be when used duplex scanning, which allows one to evaluate the contractile function of the myocardium, the nature of blood flow through the cardiac chambers and blood circulation in nearby vascular trunks.

Ultrasound is of great importance in measuring the cavities of the heart, which cannot be done using a cardiogram. Based on the results of the examination, the doctor will receive information about the sizes of the atria and ventricles in different periods contractions of the heart muscle - when the chamber is filled with blood and after the fluid is pushed into the next cavity or aorta.

It is impossible to compare the two main diagnostic methods in cardiology. Cardiogram and ultrasound provide the doctor with all necessary information to select the optimal treatment tactics. Both methods must be used before surgery and in the postoperative period.

None of them should be underestimated diagnostic techniques: in each specific case, if the doctor has prescribed a study, then it is necessary to perform an ECG and ultrasound of the heart. Often, the accuracy and speed of detection of life-threatening cardiac pathology depends on this. Or identifying positive dynamics after a long course conservative therapy, which is especially important for angina pectoris and chronic ischemic disease.

There are no unnecessary or useless diagnostic tests in cardiology. For each technique there are indications that allow you to assess the condition of the heart muscle. It is impossible to say which is better - a cardiogram or an ultrasound of the heart: one method is very different from the other, so there is no need to even try to identify one optimal method for diagnosing the pathology of the cardiovascular system. In each case and for each patient, the doctor will use a specific set of diagnostics that is most suitable for effectively identifying cardiac pathology.

Cardiogram: indications for conducting

Recording an electrocardiogram is necessary in the following cases:

  • chest pain on the left, even if the problem occurs occasionally;
  • acute sudden pain in the left side of the chest, especially if the pain radiates to the left arm or shoulder blade;
  • high blood pressure;
  • pulse rhythm disturbance;
  • constant or intermittent pressing sensations in the chest or upper abdomen;
  • at the stage of preparation for any surgical interventions;
  • control of treatment of angina pectoris and myocardial infarction;
  • for preventive purposes in all people once every 3 years (dispensary examination).

In essence, an ECG is an effective and simple method for detecting heart disease during mass medical examinations, preparation for surgical interventions, and constant monitoring of the effectiveness of conservative treatment of diseases of the cardiovascular system. In emergency situations, a person’s life depends on the speed of recording a cardiogram.

Ultrasound of the heart: indications

The undoubted advantage of ultrasound examination in comparison with other techniques is the ability to detect pathological changes in the myocardium. A cardiogram is unable to detect a severe heart defect, but an ultrasound will show the doctor serious anatomical problems of the cardiovascular system.

Ultrasound of the heart must be done in the following cases:

  • in children with suspected congenital developmental anomalies;
  • in adults to detect rheumatic or other acquired defects;
  • when symptoms of an infectious lesion of the heart cavities appear;
  • to identify post-infarction changes in the heart muscle;
  • for timely detection of aneurysms;
  • with intracardiac thrombosis;
  • with tumor formations in the breast;
  • to monitor the condition of the heart in the postoperative period.

Ultrasound of the heart is best performed in situations where there is a high risk of anatomical changes in the internal cavities and the external cardiac sac. Ultrasound can give a good effect to assess the functioning of the heart valves. Important information will be obtained when using duplex scanning, which allows assessing the contractile function of the myocardium, the nature of blood flow through the cardiac chambers and blood circulation in nearby vascular trunks.

ECG

Echocardiography (ECG) translated from Greek means “image of the heart” and is exactly what it is. Cardiac ultrasound is an ultrasound diagnostic method for studying the heart and its changes. With the advent of ultrasound diagnostic methods, research has been carried out on the possibility of using this ultrasound for imaging various organs body, including the heart. In this regard, a new direction in the study of heart function was opened - echocardiography.

During this diagnosis, special devices are used - echocardiographs (an element of this device is an ultrasound generator, through which ultrasound rays are directed through the chest to various departments hearts). An ECG allows you to determine the condition of soft tissues, as well as the thickness of the walls of the heart and its other parts. There are practically no contraindications to this study.

Procedure

An ultrasound of the heart is performed if the patient complains of pain, trembling and heart murmurs, increased fatigue, drowsiness, shortness of breath, changes in temperature in the extremities, pale skin, cyanosis.

During this procedure, the patient lies either on his back or on his left side. A sensor is located above his heart, which can change its location depending on the part of the heart being examined. A specially trained doctor who understands the topography of the heart structures, as well as changes in the heart, observes the ECG recording. The doctor must control the position of the sensor and choose the direction of the ultrasound beam.


After the procedure, the doctor must analyze the results, namely, identify the heart valves and cardiac septa, evaluate their anatomical location and movement, measure the size and determine possible deviations.

Types of ECG

There are several types of echograms of the heart, among them are aortic ECG, mitral ECG, tricuspid ECG, ECG of the left and right ventricles.

In this article we will look at the ECG (electrocardiogram) and cardiac echo (echocardiography): what is the difference between these two diagnostic procedures, in particular. Both ECG and cardiac echo are highly effective tests of the cardiovascular system.

However, despite the common goals and objectives, the methods and methods for carrying them out differ significantly. ECG and echocardiography of the heart differ from each other in the following ways:

  • by the method of conducting the research;
  • by the nature of the diseases detected;
  • on the effectiveness of monitoring the cardiovascular system.

When taking an ECG of the heart, a cardiograph and electrodes are used. An ECG examines and records the electrostatic activity of the heart muscle, and then translates the results of the study into a graphical drawing.

This picture can clearly show whether the heart exhibits a stable beating rhythm, what the numerical values ​​of the heartbeat are, and whether possible arrhythmias occur.

Cardiac arrhythmias on an ECG are visible very clearly, therefore it is the cardiographic method of studying the cardiovascular system that allows you to promptly identify cardiac arrhythmias and take appropriate measures.

Echo ECG of the heart is performed with a special electronic device- the so-called converter. The device is placed close to the chest and activated. A transducer is a generator of ultrasonic waves.

The waves emitted by the converter pass into the intracardiac structure, are reflected from the cardiac tissue and return back to the generator. Using special equipment, the converter processes the received data and displays it on the monitor in the form of a three-dimensional image.


If an ECG detects the electrostatic activity of cardiac tissues and examines heart rhythms, then an echo CG examines the ability of the cardiovascular system to pump and conduct blood through the vessels.

With the help of echo ECG, specialists can identify and prevent the development of heart failure, check the work heart valve, identify atrophied areas of the heart muscle.

An echocardiogram can examine the condition of the heart of a patient who has had an attack, identifying potential dangerous clots still blood. In addition to photographic imaging, modern echo transducers provide the ability to study the work of the heart in a dynamic 3D image.

Of course, compared to ECG, converters provide a clearer picture of the study. The method using echo devices allows us to detect the full range of heart diseases.

General principles of conducting a survey

Echocardiography or ultrasound of the heart is performed at any time that is convenient for the patient. The price for the study is low even in paid clinics. There is no need for any preliminary preparation.


Immediately before the echo kg procedure, a special conductive gel is applied to the patient’s body, which can simply be removed from the surface of the body with a napkin.

It is worth noting that ultrasound of the heart can be performed several times in a row, even within one day. This is due to the fact that the human body is not subject to any stress. Before going to the specialist’s office where echocardiography will be performed, you must take the results of the previous examination with you. A cardiogram is required. In this case, the specialist will have the opportunity to observe the process of disease development over time.

Indications for echo CG

You need to understand that you don't have to wait emergency. If your health worsens, you should immediately contact your doctor, who can prescribe the necessary tests, such as echocardiography. In this case, the chances of a correct diagnosis and correctly prescribed treatment are significantly increased.

Echo kg must be completed as quickly as possible when you discover one of the following symptoms:

  • Pain in the heart that occurs periodically or quite often
  • If you feel a feeling of heaviness or burning in the chest
  • For high blood pressure
  • In case of violation heart rate work
  • With frequent shortness of breath
  • If there is numbness in the extremities
  • When monitoring a patient’s condition after a myocardial infarction
  • If you have previously been diagnosed with heart disease

There is no need to obtain a doctor's referral to undergo this examination. Anyone can independently sign up for a heart ultrasound. Echocardiography is done to everyone on a first-come, first-served basis. However, if a specialist has given you a referral for an echo kg, then you must undergo the procedure immediately.

What can be understood from the survey results?

First of all, when performing an ultrasound of the heart, the specialist must determine the dimensions of the organ, the volume of its cavities, wall thickness, valve characteristics, as well as the presence or absence of scars, blood clots, and so on.. In this case it is necessary to pay great attention on his functional features, that is, the frequency of its impacts and other parameters.

It is also worthwhile to evaluate the general condition of the myocardium and pericardium during echo kg. Echocardiography allows you to do this. After the examination is completed, the specialist must draw up a special protocol. Thanks to it, the treating doctor can draw certain conclusions about the presence of certain pathologies or diseases. As a result, the specialist correctly diagnoses and prescribes special treatment.


Echocardiography, like ultrasound of the heart, helps to identify the following diseases:

  • Ischemic disease
  • Heart attack or pre-infarction condition
  • Hypertension or arterial hypotension
  • Congenital or acquired defects
  • Heart failure
  • Problems with rhythm
  • Rheumatism
  • Vegetative-vascular dystonia

Decoding the research results

The resulting protocol for cardiac ultrasound contains many abbreviations that only doctors can understand. For this reason, a person who does not have special education, will experience certain difficulties when trying to decipher the results of the echo kg examination. Without much difficulty, you can only estimate the standard dimensions.

It is worth noting that the norms differ for women and men. The same principle applies to children. For this reason, it is necessary to entrust the interpretation of the study results to the attending physician. Only experienced specialist will be able to evaluate the data provided and draw a conclusion about the presence of a particular disease. At the same time, he will necessarily take into account the person’s health status, his age, gender, as well as the goals of the examination. After this, an accurate or presumptive diagnosis is made.

In order to decide which method to use when cardiac problems arise: ultrasound or ECG, you need to understand how one method differs from the other. At its core it is completely different techniques. A cardiogram allows you to determine functional cardiac parameters, and an ECHO of the heart allows you to study the anatomy and structure of the organ.

Echocardiography procedure

The attending physician plays a significant role in choosing the type of examination, because it is he who determines what is best done in each case: ultrasound or other functional study. In this case, the approach to the patient must be individual. Depending on the presence of cardiac problems, the specialist draws up a plan for the necessary examination methods and their order.

Indications for echocardiography

This method is usually prescribed by a doctor, indications may be as follows:

  • if the patient is worried about weakness and dizziness;
  • he experiences fainting and frequent headaches;
  • if there is nausea with regular hypertension (increased blood pressure);
  • the patient is bothered by shortness of breath;
  • if swelling appears on the legs (mainly in the evening) or on the body;
  • periodically there is pain in the chest, subscapular region on the left, or if this symptom is constant;
  • when there is a feeling of rapid heartbeat or stopping of the heart (fading);
  • the patient has pale or bluish skin;
  • murmurs in the heart area are heard on auscultation;
  • if there are suspicions of pathological changes in the valves of the organ (congenital or acquired defect).

How is an ultrasound examination of the heart performed?

It should be added that cardiac ECHO should be performed when a patient is diagnosed with rheumatism or other systemic diseases (systemic lupus erythematosus, scleroderma).

Another reason for performing cardiac ultrasound is the condition before surgery if the patient has a history of cardiac pathology, as well as in all patients over 50 years of age.

Ultrasound is indicated in cases of vascular pathology in patients (such as varicose veins, thrombophlebitis).

Pathological changes that can be detected by ultrasound

As is known, ultrasound examination allows one to study the anatomy and structure of an organ, therefore with this method it is possible to identify:

  • anatomical features of the heart;
  • condition of the heart valves, their functionality (prolapse, regurgitation, stenosis, insufficiency);


Mitral valve stenosis

  • the state of the heart muscle during contractions and relaxations;
  • pathological changes in the organ (including tumors, microinfarctions);
  • speed indicators of blood flow in the cardiac cavities;
  • vessel diameter;
  • change in the thickness of the walls of the ventricles and atria;
  • the condition of the pericardial sac, including the presence of pathological fluid in it.

ECHO of the heart allows you to visualize blood clots in the cardiac cavities, assess the degree of atherosclerotic damage to the coronary vessels, and the presence of accessory chordae, which are considered a normal variant. Also, with echocardiography, you can assess the condition of large vessels, that is, this method shows changes in the aorta.

Thus, cardiac ECHO allows us to identify many cardiac diseases. It should be added that the established norm during ultrasound is influenced individual characteristics the patient, physique, and also his age.

Changes that are detected by ECG


A man undergoes an ECG

It should be noted that ECG machines are widely available, the procedure lasts a few minutes, and is quite simple, unlike ultrasound. The following changes can be identified:

  • heart rhythm disturbances (tachy- or bradyarrhythmia, ecstasystole, atrial fibrillation);
  • signs of myocardial ischemia (myocardial infarction, as well as coronary heart disease);
  • signs of blockade (improper conduction of impulses).

Along with this, the cardiogram does not show changes that were not present at the time the ECG was recorded (but were present in the patient some time ago). As well as pathology that is not manifested by electrical manifestations (for example, low degrees of valve defects). These pathological changes can be detected when performing cardiac echo.

An ECG does not always show changes in the walls of the ventricles and atria, manifested by their thickening, as well as pronounced functional changes in heart defects. These signs are better identified with cardiac ECHO.

It should be noted that the cardiogram may reveal false positive results, that is, some acute pathology, which in fact does not exist. This may primarily occur in women during menopause. Attention! This pathology has been recorded on the ECG for years.

Another reason false positive result on the cardiogram is registration ischemic changes in patients with autoimmune diseases rheumatic diseases. These pathological changes are observed for a long time, although in fact the patient’s electrocardiogram is normal.

It is recommended to perform electrocardiography in patients who have had a sore throat (since the causative agent of the disease has a tropism for the cardiac cavities). At the same time, this functional study can detect coronary complications on early stage when possible complete cure. In this situation, cardiac ECHO should also be performed.

In conclusion, I would like to emphasize the special role of the heart for our body. It cannot be replaced, and restoring full operation can be extremely difficult. Therefore, when the first interruptions in its work appear, you must immediately contact a cardiologist and undergo the appropriate examination: ECG, ultrasound or other methods.

Using an ECG, you can identify the following disturbances in the functioning of the cardiovascular system:

  • Heart rhythm disturbances (arrhythmia, tachycardia, atrial fibrillation, extrasystole).
  • Disturbances in myocardial nutrition (ischemia, myocardial infarction).
  • Impulse conduction disorder (antiventricular block).
  • Displacement of the heart axis (hypertrophy with different localization).
  • Thickening of the myocardium (ventricular and atrium hypertrophy).
  • Congenital and acquired defects (impairments in the structure of the valves, fibrous ring and notochord).

Persons over 40 years of age must undergo an electrocardiogram every year. This will help install functional state cardiovascular system and identify possible disorders at the initial stage.

The study is very effective and indicative, but despite this, to clarify the condition of the myocardium, it is necessary to resort to ultrasound diagnostics of the heart.

Diagnosis of the heart using ultrasound

Ultrasound examination of the heart is a fairly young method in cardiology, which medical practice called echocardiography. The procedure is carried out using a special device - an electrocardiograph; it generates ultrasound, the rays of which penetrate through the chest, determining the condition of the soft tissues and the thickness of the myocardium. The technique is safe for the patient and has high information content and reliability of the results obtained.


The method allows you to determine not only the condition of the vessels and walls of the myocardium, but also the speed of blood movement in this period time

Indications for the procedure:

  • congenital heart pathologies in children;
  • acquired heart disease in adults;
  • the presence of symptoms of infectious damage to the heart muscle;
  • clarification of the diagnosis of “heart attack”;
  • assessment of the state of the myocardium after a heart attack;
  • detection of intracardiac artery thrombosis;
  • neoplasms in the chest cavity;
  • monitoring the state of the myocardium in the postoperative period.

Using ultrasound of the heart muscle, the following pathological conditions can be determined:

  • identification of hidden heart defects;
  • violation of the integrity of external and inner shells organ;
  • enlargement and thickening of the myocardium;
  • pathological changes in the contractility of the organ;
  • accumulation of fluid in the heart cavity;
  • establishing the nature and speed of blood flow through the chambers and aortas of the organ.


The disadvantage of the procedure is the inability to establish possible violations passage of electrical impulses

Modern techniques make it possible to identify the slightest disturbances in the functioning of the organ, which are difficult to establish using a cardiogram.

Which method should be preferred?

Ultrasound of the heart and ECG are the two main diagnostic methods in cardiology, based on their results, the specialist assesses the degree of organ damage and chooses the optimal treatment approaches.


Both diagnostic methods are required before surgery.

The data obtained from both studies are highly informative, but the ultrasound results are still more meaningful. Therefore, before starting diagnostics of the cardiovascular system, you should visit a cardiologist, who, based on complaints, will be able to select the necessary technique. In most cases, the primary procedure is electrocardiography, since it can provide the doctor with all the information about the condition of the heart muscle. If the cardiologist has doubts and needs additional information, then he prescribes the patient to undergo an ultrasound.

Thus, the two methods are independent of each other; every person must undergo them, especially if there are complaints about the work of the organ. Thus, timely detection of heart disease at an early stage will help prevent the occurrence of more serious complications.

ECG and ultrasound of the heart - two independent method examinations that should not be divided into worst and best.

ECG – electrocardiogram

ECG is an examination method based on the conduction of heart impulses. Previously, 100 years ago, when the invention of the ECG machine was awarded Nobel Prize, patients had to immerse their arms and legs in a container of water to record a cardiogram. Currently, science does not stand still and more compact devices have been invented, but the number of wires, electrodes and holders has not decreased.

Taking an ECG

There are only 5 electrodes that are used to record the ECG at rest, but a lead and ground are also present. Each of these elements is important and the absence of at least one may not only prevent the device from registering normal cardiogram, but also cause physical harm to the patient.

What will an ECG reveal?

  • Rhythm disorders

Arrhythmia (pathology associated with rhythm disturbances, which manifests itself in the form of irregular heartbeats), tachycardia (disorder associated with an increase in the number of heartbeats), bradycardia (disorder associated with a decrease in the number of heartbeats), atrial fibrillation, extrasystole (extraordinary heartbeat with a long pause after).


Various heart rhythm disturbances

  • Disturbances in the trophism of the heart muscle

The phenomenon of insufficient supply of oxygen and nutrients to the muscle, during its increased, intensified or normal work, is called ischemia. Its acute manifestation is myocardial infarction, which in most cases leads to death or serious problems in the future and even disability.

  • Impaired conduction of impulses

Disturbances in the conduction of electrical impulses through the conduction system are expressed in blockades, which are clearly visible on the cardiogram. The heart has several nodes that generate an electrical impulse, thanks to which automation occurs (independent contraction). The main one is the atrioventricular one. If it is damaged, the impulse does not reach some structures of the heart, which can subsequently lead to atrophy. Therefore, it is important to know about the operation of the conduction system.

  • Heart axis displacement

A displacement of the axis indicates hypertrophy of some sections and resulting pathologies.

  • Thickening of the muscle wall of the components (ventricles or atria)

Hypertrophy of individual components indicates pathologies and problems in the cardiovascular system. Early detection of wall thickening will prevent the development of serious diseases that have not yet manifested themselves clinically.


Increasing the thickness of the heart muscle

  • Heart defects

Basically, a cardiogram allows you to identify already advanced stages of defects associated with the valve apparatus.

What can't an ECG detect?

  • Disturbances in the functioning of the heart that do not manifest themselves in this moment. For such cases, when failures occur at the time of emotional stress or physical activity, there is Holter or long-term 24-hour monitoring.
  • Heart defects, especially the valve apparatus, in the early stages of development.
  • Sometimes false positive results are possible and require separate consideration.

Ultrasound of the heart - ultrasound examination

Ultrasound is a relatively new technique for examining patients with cardiovascular diseases. But despite its young age, it is highly informative, reliable and safe. Only ultrasound allows you to see all the components and structures of the heart in real time. Allows you to see the operation of the valve apparatus, contraction and relaxation of the ventricles and atria, and the movement of blood through the vessels.

What will a heart ultrasound allow you to see?

  • Heart defects

The main task of ultrasound is to identify defects that have not yet manifested themselves clinically and are not visible on the cardiogram.

  • Detection of coronary artery disease and damage to the outer and muscular lining of the heart

Damage or the degree or stage of development of diseases such as ischemic disease (one of the outcomes of which is myocardial infarction), angina pectoris, pericarditis, myocarditis (inflammation of the muscular membrane or pericardium) are assessed.

  • Dimensions and volumes of components

Ultrasound allows you to determine the thickness of the walls of the ventricles and atria down to millimeters, find out their volumes, and see damage to the valves.

  • Assess contractility

Allows you to visually see the severity of contractions and relaxations of the heart components.

  • Presence of fluid in the pericardium.


Echocardiography procedure

What can't an ultrasound detect?

The possibilities of ultrasound examination are so great that almost all pathologies can be detected using this examination method. The exception is disorders that are associated with the conduction of electrical impulses through the conduction system of the heart. This type of disorder plays, if not the main, then one of the most important reasons in the development of cardiovascular diseases.

Heart ultrasound and cardiogram are two independent examination methods that every patient with heart problems should undergo. If a doctor has prescribed it for you, but you have no clinical manifestations, you should not ignore it; ultrasound and ECG can identify diseases and pathologies on the early stages development and proper treatment will prevent the development serious complications. Ultrasound and cardiogram are complementary methods of examination - if the pathology is not diagnosed in one case, it is not a fact that it will not be expressed in another.

What is better - ECG or ultrasound of the heart, the cardiologist decides individually. If you ask a doctor this question, he will most likely answer that this formulation is not entirely correct, since both of these diagnostic procedures are very important. ECG or electrocardiography can detect some heart diseases that can be life-threatening, and ultrasound can detect others. Doctors often prescribe both procedures to get full information about the work of the heart.

Diagnosis using electrocardiography

An ECG is a simple and painless procedure performed using a cardiograph. The Dutch scientist Willeim Einthoven designed the first apparatus for electrocardiography in 1903. This diagnostic method is based on recording fluctuations caused by the work of the heart. Information is transmitted through electrodes to the cardiograph. The difference between the oscillation potentials of the heart muscle is the leads that are recorded after applying electrodes to the chest in the area of ​​the heart and limbs.

An ECG machine records electrical impulses and displays them as a graphical curve on thermal paper. There are 12 leads in total that allow you to see the work of different parts of the heart muscle. Electrocardiography is effective for detecting heart diseases, is in demand during medical examinations, and is necessary before surgical intervention. An ECG is also prescribed after treatment to see how effective the therapy was. In emergency cases, a person’s life depends on the speed of the procedure.

    Indications for an electrocardiogram are;

    • routine examination;
    • hypertension;
    • IHD (coronary heart disease);
    • myocardial infarction;
    • heart defects of various etiologies;
    • cardiomyopathy caused by endocrine disorders;
    • chronic heart failure;
    • heart rhythm disturbances (tachycardia, arrhythmia, bradycardia);
    • pericarditis;
    • control after cardiac surgery.

    These diseases may be accompanied by shortness of breath, pain in the chest, fatigue, coughing for no reason, dizziness, nausea, and a burning sensation in the stomach. With such complaints, the doctor may refer the patient to undergo electrocardiography.


    In what cases is echocardiography necessary?

    Everything in cardiology diagnostic procedures very important. The difference lies in the equipment and method of implementation. Each technique has its own indications that allow you to determine the state of the cardiovascular system. Before the advent of ultrasound, the only available method was electrocardiography, so some pathologies could not be diagnosed. With the advent of ultrasound, it became possible to obtain more information about the condition of the heart muscle.


      Ultrasound examination is also a safe diagnostic method. Thanks to this procedure, the doctor sees in real time:

      • condition of the heart and valve apparatus;
      • the size of the cavities of the heart muscle;
      • wall thickness;
      • speed and direction of blood flow.

      Thanks to echodiagnosis, general and local contractile activity is measured and assessed. The most common procedure is transthoracic echocardiography, which means the procedure is done through the surface of the body. For certain pathologies, transesophageal echocardiography, called transesophageal from lat. Oesophagus. Ultrasound allows you to perform stress tests called stress echoes.

      The patient's load is specially increased with the help of medications or physical exercises to fix the changes that occur in the work of the heart in this mode. This method of examination helps to identify hidden pathological phenomena that go unnoticed in relatively calm state. Heart ultrasound is prescribed for:

        • signs of left-right ventricular failure;
        • the presence of pathological noises when listening;
        • IHD of a chronic or acute nature;
        • myocardial infarction;
        • heart rhythm disturbances;
        • septic conditions;
        • chest injuries;
        • chest pain of unknown origin;
        • thrombosis of the main deep veins;
        • treatment with antibiotics for cancer;
        • suspected aortic aneurysm.


        There is a group of patients who complain of chronic headaches. This procedure is carried out in order to exclude pathological change atrial septum, due to which microebola (blood clots) appear.

        Which examination method is more important?

        Although both diagnostic procedures described are important, sometimes there are nuances that doctors take into account before prescribing. In a critical situation, when the ambulance team is responding to a call, a cardiogram of the heart is taken. The device is located in the car, so in case of accidents, hypertensive crisis, or suspected myocardial infarction, it can be done at home or on the way to the hospital. The examination carried out using the situation helps to assess the patient’s condition and provide the necessary assistance immediately.


        When the crisis has passed, the patient is recommended to undergo additional examination using ultrasound. You should not refuse this procedure. Modern equipment allows you to see the smallest disorders that cannot be detected only with the help of an electrocardiogram. If the cardiologist prescribes only an ultrasound, check whether other procedures should be used.

        Some patients are prescribed 24-hour monitoring, that is, a small sensor is attached to the patient’s body, which records all indicators of heart function throughout the day. This method helps to see how the heart muscle works during the day during the patient’s everyday load. A regular electrocardiogram does not allow recording extrasystole, especially if it is an episodic phenomenon. Holter monitoring is performed for complaints of myocardial ischemia and tachycardia.

        The study through the esophagus is abbreviated as TES (transesophageal pacing) and has been used by doctors for about 30 years. This method diagnostic differs in that a sterile electrode is inserted directly into the esophagus, closer to the heart. After its introduction to a depth of 40 cm, the doctor delivers weak electrical impulses, gradually increasing the frequency of contractions. All conduction system data is recorded and then deciphered by a specialist. If during the diagnosis a strong heartbeat occurs, the procedure is stopped.

It is difficult to say for sure which is better – ultrasound or ECG of the heart. These are two similar procedures. They allow you to conduct early diagnosis and identify abnormalities in the functioning of the cardiovascular system. What is better is an ultrasound of the heart or a cardiogram - the doctor determines.

This type of examination is an excellent preventative tool. It allows you to identify the disease in the early stages of development. This is a quick and easy way to get information about the state of the cardiovascular system. Diagnostics are carried out using modern equipment. Ultrasound (echocardiography) allows you to see not only the structure of blood vessels, but also observe the movement of blood in them.

This study is applicable to:

  • detection of the disease at an early stage;
  • making an accurate diagnosis.

This method completely replaces x-ray research methods. Thus, a person completely gets rid of radiation exposure. The technique is absolutely safe and has no side effects.

Main indications for using ultrasound:

  • heart murmurs of unknown origin;
  • symptoms of congenital or acquired heart defects;
  • heart failure;
  • suspicion of a tumor;
  • assessment of the results of previous surgical intervention;
  • general state of cardio-vascular system;
  • study of arterial hypertension.

There are no contraindications for the study. It is widely used to assess the state of the cardiovascular system in both adults and children.

Ultrasound allows you to determine the structure of the heart, accurately showing the sizes of all its components. When researching Special attention is paid to the parameters of the organ and the frequency of beats. The general condition of the myocardium and pericardium, large vessels and atria is assessed. This allows us to identify pathological changes in the development and functioning of the heart muscle.

Ultrasound is widely used to detect cardiac arrhythmias, vegetative-vascular dystonia, rheumatism and coronary disease. This technique is informative and safe, so it is one of the leading ones in the field of cardiology.

heart electrocardiogram

This method allows you to identify diseases of the cardiovascular system in the early stages. The human heart works in a certain rhythm, producing electrical impulses. A failure in this process is recorded by an electrocardiogram. Thanks to this study, it is possible to record the language of the myocardium.

Any deviations in the development of the P, Q, R, S and T waves make it possible to determine possible diseases of cardio-vascular system.

Electrocardiograms are prescribed by a doctor. Most often, the need for examination arises after a visit to a cardiologist. Main indications for the procedure:

  • severe pain in the heart, chest and back;
  • discomfort;
  • constant shortness of breath;
  • unstable heart function;
  • diabetes;
  • rheumatism;
  • previous stroke.

Electrocardiography may be performed as part of a routine examination. This is necessary during pregnancy, before surgery and exercise. active species sports People over 40 years of age need to be examined annually. This will allow you to monitor the functioning of the cardiovascular system and identify possible deviations in it at an early stage.

A cardiogram allows you to obtain information about the functionality of the heart (beat frequency, condition of the heart muscle and general condition of the organ). These parameters are the main ones in the work of the heart. The examination allows you to obtain accurate data regarding heart rate. It shows what rhythm the heart beats. This information can be obtained using special electrodes that are attached to the human body. During the examination, the condition of the heart muscle is assessed.

Despite the effectiveness of the study, you should not limit yourself to these data only. To confirm the preliminary diagnosis, it is necessary to resort to additional diagnostic techniques.

Ultrasound or ECG – what determines the choice?

Or what is the difference between an ECG and an ultrasound? There is no particular difference in these methods. They are aimed at identifying pathological processes in the cardiovascular system. During an ECG, a special device called an electrocardiograph is used. It is an ultrasound generator, passing them through the chest and recording data on different areas hearts. The technique is aimed at determining the condition of the soft tissues, as well as the thickness of the organ itself. There are no contraindications to the use of ECG.

An ultrasound examination is performed for certain patient complaints. It is used for pain, heart murmurs and increased fatigue. All of these symptoms, including drowsiness and shortness of breath, may indicate serious abnormalities in the heart. During the procedure, the patient must be in a lying position. A special sensor is attached above the heart, the location of which depends on the area of ​​concern.

After the procedure, based on the data obtained, the specialist determines the functionality of the heart, anatomical location and valve movement. This allows you to record possible abnormalities in the organ.

ECG and ultrasound are almost identical procedures; their action is aimed at identifying diseases of the cardiovascular system. The doctor decides which diagnostic method to use depending on the patient’s complaints and condition. Overall, these research methods work together to produce informative data.

What is better - an ultrasound of the heart or a cardiogram - is determined by the doctor.

Which is better – ECG or ultrasound of the heart?

Diseases of the cardiovascular system are the most common among the population, both young and old. Therefore, when visiting a cardiologist, examinations are mandatory that help establish the functional capacity of the heart muscle. Most informative methods Ultrasound and electrocardiogram are considered. However, most patients are wondering whether it is necessary to do two procedures at the same time and what is better: cardiac ultrasound or ECG? Let's try to figure out which method is the best today.

Indications for cardiac examination

Tests are carried out strictly in accordance with the direction of the cardiologist. A visit to a specialist can be either planned or in case of complaints of malfunctions in the cardiovascular system.

Most frequent symptoms with impaired heart function:

  • Compressive pain behind the sternum and in the region of the heart, radiating to the scapular area.
  • Rapid pulse, which manifests itself as palpitations, and dizziness.
  • Dry barking cough.
  • Periodic loss of consciousness.
  • Edema of the lower extremities.

Close attention should be paid to patients with a history of stroke, congenital heart abnormalities and rheumatism.

The specialist conducts an examination and refers for research if the following factors are identified:

The following categories of people are required to conduct research:

  • The presence of congenital or acquired diseases of the cardiovascular system.
  • Women during pregnancy.
  • Patients before planned operations.
  • Athletes due to heavy workload.

The cardiologist chooses which is better, ultrasound of the heart or ECG, since both methods are actively used in practice. They are highly informative, the assessment of results is reliable and accurate, but still the electrocardiogram is paramount. If a pathology is detected, the doctor prescribes an ultrasound to clarify the diagnosis. To determine which method is most effective, you need to familiarize yourself with the principle of each of them.

Features of diagnostics using ECG

The principle of the method is based on recording electronic heart impulses that occur during myocardial contraction. The resulting impulses are read by a cardiograph, displaying them in the form of a graphic curve on special paper with a scale.

  1. Before starting the procedure, you must remove your jewelry.
  2. Expose the area of ​​the hands, ankles and chest.
  3. Accept horizontal position and relax as much as possible.
  4. Before applying the electrodes, the nurse treats open areas skin with a cotton pad moistened with water for better conduction of impulses.
  5. Then applies 4 electrodes different color on the limbs in a certain order.
  6. Electrodes are fixed on the chest using 6 suction cups.
  7. Then the electrodes are connected to the device, after which they are registered.

A cardiogram is effective in identifying diseases of cardiac origin, is relevant for preventive examinations, and is mandatory before surgery.

Using an ECG, you can identify the following disturbances in the functioning of the cardiovascular system:

  • Heart rhythm disturbances (arrhythmia, tachycardia, atrial fibrillation, extrasystole).
  • Disturbances in myocardial nutrition (ischemia, myocardial infarction).
  • Impulse conduction disorder (antiventricular block).
  • Displacement of the heart axis (hypertrophy with different localization).
  • Thickening of the myocardium (ventricular and atrium hypertrophy).
  • Congenital and acquired defects (impairments in the structure of the valves, fibrous ring and notochord).

The study is very effective and indicative, but despite this, to clarify the condition of the myocardium, it is necessary to resort to ultrasound diagnostics of the heart.

Diagnosis of the heart using ultrasound

Ultrasound examination of the heart is a fairly new method in cardiology, which in medical practice is called echocardiography. The procedure is carried out using a special device - an electrocardiograph; it generates ultrasound, the rays of which penetrate through the chest, determining the condition of the soft tissues and the thickness of the myocardium. The technique is safe for the patient and has high information content and reliability of the results obtained.

Indications for the procedure:

  • congenital heart pathologies in children;
  • acquired heart disease in adults;
  • the presence of symptoms of infectious damage to the heart muscle;
  • clarification of the diagnosis of “heart attack”;
  • assessment of the state of the myocardium after a heart attack;
  • detection of intracardiac artery thrombosis;
  • neoplasms in the chest cavity;
  • monitoring the state of the myocardium in the postoperative period.

Using ultrasound of the heart muscle, the following pathological conditions can be determined:

  • identification of hidden heart defects;
  • violation of the integrity of the outer and inner membranes of the organ;
  • enlargement and thickening of the myocardium;
  • pathological changes in the contractility of the organ;
  • accumulation of fluid in the heart cavity;
  • establishing the nature and speed of blood flow through the chambers and aortas of the organ.

Modern techniques make it possible to identify the slightest disturbances in the functioning of the organ, which are difficult to establish using a cardiogram.

Which method should be preferred?

Ultrasound of the heart and ECG are the two main diagnostic methods in cardiology; based on their results, the specialist assesses the degree of damage to the organ and selects the optimal treatment approaches.

The data obtained from both studies are highly informative, but the ultrasound results are still more meaningful. Therefore, before starting diagnostics of the cardiovascular system, you should visit a cardiologist, who, based on complaints, will be able to select the necessary technique. In most cases, the primary procedure is electrocardiography, since it can provide the doctor with all the information about the condition of the heart muscle. If the cardiologist has doubts and needs Additional Information, then he prescribes the patient to undergo an ultrasound.

Thus, the two methods are independent of each other; every person must undergo them, especially if there are complaints about the work of the organ. Thus, timely detection of heart disease at an early stage will help prevent the occurrence of more serious complications.

Which method is preferable for examining the heart: ultrasound or ECG?

In order to decide which method to use when cardiac problems arise: ultrasound or ECG, you need to understand how one method differs from the other. At their core, these are completely different methods. A cardiogram allows you to determine functional cardiac parameters, and an ECHO of the heart allows you to study the anatomy and structure of the organ.

The attending physician plays a significant role in choosing the type of examination, because it is he who determines what is best done in each case: ultrasound or other functional research. In this case, the approach to the patient must be individual. Depending on the presence of cardiac problems, the specialist draws up a plan necessary methods examinations and their order.

Indications for echocardiography

This method is usually prescribed by a doctor, indications may be as follows:

  • if the patient is worried about weakness and dizziness;
  • he experiences fainting and frequent headaches;
  • if there is nausea with regular hypertension (increased blood pressure);
  • the patient is bothered by shortness of breath;
  • if swelling appears on the legs (mainly in the evening) or on the body;
  • periodically there is pain in the chest, subscapular region on the left, or if this symptom is constant;
  • when there is a feeling of rapid heartbeat or stopping of the heart (fading);
  • the patient has pale or bluish skin;
  • murmurs in the heart area are heard on auscultation;
  • if there are suspicions of pathological changes in the valves of the organ (congenital or acquired defect).

It should be added that cardiac ECHO should be performed when a patient is diagnosed with rheumatism or other systemic diseases(systemic lupus erythematosus, scleroderma).

Another reason for performing cardiac ultrasound is the condition before surgery if the patient has a history of cardiac pathology, as well as in all patients over 50 years of age.

Ultrasound is indicated in cases of vascular pathology in patients (such as varicose veins, thrombophlebitis).

Pathological changes that can be detected by ultrasound

As is known, ultrasound examination allows one to study the anatomy and structure of an organ, therefore with this method it is possible to identify:

  • anatomical features of the heart;
  • condition of the heart valves, their functionality (prolapse, regurgitation, stenosis, insufficiency);
  • the state of the heart muscle during contractions and relaxations;
  • pathological changes in the organ (including tumors, microinfarctions);
  • speed indicators of blood flow in the cardiac cavities;
  • vessel diameter;
  • change in the thickness of the walls of the ventricles and atria;
  • the condition of the pericardial sac, including the presence of pathological fluid in it.

ECHO of the heart allows you to visualize blood clots in the cardiac cavities and assess the degree of atherosclerotic lesions coronary vessels, the presence of additional chords, which are considered a variant of the norm. Also, echocardiography can assess the condition of large vessels, that is, this method shows changes in the aorta.

Thus, cardiac ECHO allows us to identify many cardiac diseases. It should be added that the established norm for ultrasound is influenced by the individual characteristics of the patient, physique, as well as his age.

Changes that are detected by ECG

It should be noted that ECG machines are widely available, the procedure lasts a few minutes, and is quite simple, unlike ultrasound. The following changes can be identified:

  • heart rhythm disturbances (tachy- or bradyarrhythmia, ecstasystole, atrial fibrillation);
  • signs of myocardial ischemia (myocardial infarction, as well as coronary heart disease);
  • signs of blockade (improper conduction of impulses).

Along with this, the cardiogram does not show changes that were not present at the time the ECG was recorded (but were present in the patient some time ago). As well as pathology that is not manifested by electrical manifestations (for example, low degrees of valve defects). These pathological changes can be detected when performing cardiac echo.

An ECG does not always show changes in the walls of the ventricles and atria, manifested by their thickening, as well as pronounced functional changes in heart defects. These signs are better identified with cardiac ECHO.

It should be noted that the cardiogram may reveal false positive results, that is, some kind of acute pathology that actually does not exist. This may primarily occur in women during menopause. Attention! This pathology has been recorded on the ECG for years.

Another reason for a false positive result on the cardiogram is the registration of ischemic changes in patients with autoimmune rheumatic diseases. These pathological changes are observed for a long time, although in fact the patient’s electrocardiogram is normal.

It is recommended to perform electrocardiography in patients who have had a sore throat (since the causative agent of the disease has a tropism for the cardiac cavities). Moreover, this functional study can detect coronary complications at an early stage, when their complete cure is possible. In this situation, cardiac ECHO should also be performed.

In conclusion, I would like to emphasize the special role of the heart for our body. It cannot be replaced, and restoring full operation can be extremely difficult. Therefore, when the first interruptions in its work appear, you must immediately contact a cardiologist and undergo the appropriate examination: ECG, ultrasound or other methods.

What is better to do in case of heart problems: ECG or ultrasound?

When heart problems begin, people consult a doctor. The cardiologist has wide range procedures that can be offered to the patient for examination. What is better to do: ECG or ultrasound of the heart? How are these procedures different? Is it possible to do without one of them? We will consider the answers to these questions.

General information about procedures

There are no unnecessary techniques in cardiac examinations. Although many different research methods are used, each has its own advantages, disadvantages, indications and contraindications. Sometimes an accurate diagnosis is only possible with comprehensive examination using several methods at the same time.

More about ECG

An ECG is performed using a special device - an electrocardiograph. The first device appeared back in 1903. The cardiograph records fluctuations caused by the work of the heart. Data enters the device through special electrodes, which are attached to the patient’s body before the procedure. ECG is safe and painless.

ECG results are a curved line that reflects the conduction of impulses. Typically the procedure is performed in 12 leads. An electrocardiogram helps to identify heart pathologies in the early stages and monitor the condition of the heart before surgical interventions. The procedure is also needed to determine how effective a particular therapy is.

More details about how an ECG is performed are shown in the video:

More about ultrasound

Although an electrocardiogram provides a detailed picture of the functioning of the heart muscle, the procedure cannot diagnose absolutely all pathologies. Until ultrasound equipment was invented, some serious illnesses It was not possible to determine what cost many their lives.

An ultrasound examination does not allow one to evaluate the work of the heart at the moment, but it makes it possible to see what condition the organ is in, how its valves work, what is the size of the muscle and the thickness of the walls of the heart.

Ultrasound of the heart allows you to see what the contractility of the heart is, whether the pressure inside is normal pulmonary artery. This procedure is safe for the patient and does not cause pain.

Sometimes cardiologists use stress ultrasound. With this examination, the study is carried out first in a calm state, and then after exercise. Changing indicators helps to assess the condition of the heart and its reaction to the occurrence of irritating factors.

Indications for procedures

Both ultrasound and ECG are prescribed for cardiac pathologies and suspicions of them. Both procedures are allowed for adults and small children. ECG and ultrasound are painless and harmless, they give a complete picture of the condition and functioning of the heart muscle.

Indications for ECG

You should not refuse an ECG if this procedure is prescribed by a doctor or suggested by an ambulance representative. medical care. Although the technique is often used for routine examination and treatment, it is effective in providing emergency assistance. Since this method gives immediate results, an ECG is indicated:

  • for hypertension;
  • if myocardial infarction is suspected;
  • for angina pectoris;
  • with coronary heart disease;
  • with post-infarction cardiosclerosis;
  • with pericarditis;
  • for arrhythmic manifestations, including tachycardia, bradycardia;
  • for heart failure.

ECG with frequent intervals held in postoperative periods, especially if cardiac surgery has been performed.

Endocrine disorders often cause complications on the myocardium. Therefore, a cardiac cardiogram is also prescribed for diseases of the thyroid system. The procedure is important in the presence of heart defects, congenital and acquired.

An ECG, even when there is no heart disease, is recommended for the following symptoms:

  • fast fatiguability;
  • dyspnea;
  • frequent nausea;
  • dizziness;
  • causeless cough;
  • burning in the stomach area.

And ultrasound of the heart and ECG - important procedures when diagnosing cardiovascular pathologies. It remains to be understood when an ultrasound examination of this organ is performed.

Indications for ultrasound

If you understand the difference between an ultrasound and an ECG, then the doctor’s prescription will not come as a surprise. The difference is that different equipment is used when performing the procedures, and it produces completely different characteristics.

What does ultrasound show, and for what pathologies is it prescribed? Here is a list of the main indications:

  • myocardial infarction;
  • pathological murmurs when listening to the heart;
  • intraventricular failure;
  • acute or chronic ischemic heart disease;
  • arrhythmia;
  • chest injuries;
  • pain of an unspecified nature;
  • deep vein thrombosis;
  • aortic aneurysm.

The difference between this procedure and others is that the results can show the presence or absence of a tumor, cyst, blood clot inside an organ or blood vessels. Ultrasound allows you to clearly identify the location of the heart attack and make a detailed prognosis.

Sometimes patients complain of regular, severe headaches. Then doctors also recommend performing an ultrasound of the heart. This study will show whether there are changes in the heart that are accompanied by the appearance of microemboli.

Where to begin

At serious problems With the heart, doctors recommend both procedures. An ECG can be performed even when an ambulance leaves, because the device is in the car. An ultrasound is performed after acute phase will pass, and the patient will be taken to the hospital department.

If the examination is carried out on time, serious illnesses can be found on initial stages and prevent the condition from getting worse.

How does a cardiac ultrasound differ from a cardiogram?

There are no unnecessary or useless diagnostic tests in cardiology. For each technique there are indications that allow you to assess the condition of the heart muscle. It is impossible to say which is better - a cardiogram or an ultrasound of the heart: one method is very different from the other, so there is no need to even try to identify one optimal method for diagnosing the pathology of the cardiovascular system. In each case and for each patient, the doctor will use a specific set of diagnostics that is most suitable for effectively identifying cardiac pathology.

Cardiogram: indications for conducting

Recording an electrocardiogram is necessary in the following cases:

  • chest pain on the left, even if the problem occurs occasionally;
  • acute sudden pain in the left side of the chest, especially if the pain radiates to the left arm or shoulder blade;
  • high blood pressure;
  • pulse rhythm disturbance;
  • constant or intermittent pressing sensations in the chest or upper abdomen;
  • at the stage of preparation for any surgical interventions;
  • control of treatment of angina pectoris and myocardial infarction;
  • for preventive purposes in all people once every 3 years (dispensary examination).

In essence, an ECG is an effective and simple method for detecting heart disease during mass medical examinations, preparation for surgical interventions, and constant monitoring of the effectiveness of conservative treatment of diseases of the cardiovascular system. In emergency situations, a person’s life depends on the speed of recording a cardiogram.

Ultrasound of the heart: indications

The undoubted advantage of ultrasound examination in comparison with other techniques is the ability to detect pathological changes in the myocardium. A cardiogram is unable to detect a severe heart defect, but an ultrasound will show the doctor serious anatomical problems of the cardiovascular system.

Ultrasound of the heart must be done in the following cases:

  • in children with suspected congenital developmental anomalies;
  • in adults to detect rheumatic or other acquired defects;
  • when symptoms of an infectious lesion of the heart cavities appear;
  • to identify post-infarction changes in the heart muscle;
  • for timely detection of aneurysms;
  • with intracardiac thrombosis;
  • with tumor formations in the breast;
  • to monitor the condition of the heart in the postoperative period.

Ultrasound of the heart is best performed in situations where there is a high risk of anatomical changes in the internal cavities and the external cardiac sac. Ultrasound can give a good effect to assess the functioning of the heart valves. Important information will be obtained when using duplex scanning, which allows assessing the contractile function of the myocardium, the nature of blood flow through the cardiac chambers and blood circulation in nearby vascular trunks.

Ultrasound is of great importance in measuring the cavities of the heart, which cannot be done using a cardiogram. Based on the results of the examination, the doctor will receive information about the sizes of the atria and ventricles at different periods of contraction of the heart muscle - when the chamber is filled with blood and after the fluid is pushed into the next cavity or aorta.

It is impossible to compare the two main diagnostic methods in cardiology. A cardiogram and ultrasound provide the doctor with all the necessary information to choose the optimal treatment tactics. Both methods must be used before surgery and in the postoperative period.

None of the diagnostic methods should be underestimated: in each specific case, if the doctor has prescribed a study, then it is imperative to perform an ECG and ultrasound of the heart. Often, the accuracy and speed of detection of life-threatening cardiac pathology depends on this. Or identifying positive dynamics after a long course of conservative therapy, which is especially important for angina pectoris and chronic ischemic disease.

What is better to do an ECG or ultrasound of the heart and what is the difference between these procedures?

What is better, an ECG or an ultrasound of the heart, is decided by the cardiologist individually. If you ask a doctor this question, he will most likely answer that this formulation is not entirely correct, since both of these diagnostic procedures are very important. ECG or electrocardiography can detect some heart diseases that can be life-threatening, and ultrasound can detect others. Doctors often prescribe both procedures to obtain complete information about the functioning of the heart.

An ECG is a simple and painless procedure performed using a cardiograph. The Dutch scientist Willeim Einthoven designed the first apparatus for electrocardiography in 1903. This diagnostic method is based on recording fluctuations caused by the work of the heart. Information is transmitted through electrodes to the cardiograph. The difference between the oscillation potentials of the heart muscle is the leads that are recorded after applying electrodes to the chest in the area of ​​the heart and limbs.

An ECG machine records electrical impulses and displays them as a graphical curve on thermal paper. There are 12 leads in total that allow you to see the work of different parts of the heart muscle. Electrocardiography is effective for detecting heart diseases, is in demand during medical examinations, and is necessary before surgery. An ECG is also prescribed after treatment to see how effective the therapy was. IN in case of emergency A person’s life depends on the speed of the procedure.

Indications for an electrocardiogram are;

  • routine examination;
  • hypertension;
  • IHD (coronary heart disease);
  • myocardial infarction;
  • post-infarction cardiosclerosis;
  • heart defects of various etiologies;
  • cardiomyopathy caused by endocrine disorders;
  • chronic heart failure;
  • heart rhythm disturbances (tachycardia, arrhythmia, bradycardia);
  • pericarditis;
  • control after cardiac surgery.

These diseases may be accompanied by shortness of breath, pain in the chest, fatigue, coughing for no reason, dizziness, nausea, and a burning sensation in the stomach. With such complaints, the doctor may refer the patient to undergo electrocardiography.

In cardiology, all diagnostic procedures are very important. The difference lies in the equipment and method of implementation. Each technique has its own indications that allow you to determine the state of the cardiovascular system. Before the advent of ultrasound, the only available method was electrocardiography, so some pathologies could not be diagnosed. With the advent of ultrasound, it became possible to obtain more information about the condition of the heart muscle.

Ultrasound examination is also a safe diagnostic method. Thanks to this procedure, the doctor sees in real time:

  • condition of the heart and valve apparatus;
  • the size of the cavities of the heart muscle;
  • wall thickness;
  • speed and direction of blood flow.

Thanks to echodiagnosis, pressure in the pulmonary artery is measured, general and local contractile activity is assessed. The most common procedure is transthoracic echocardiography, which means the procedure is done through the surface of the body. For certain pathologies, transesophageal echocardiography, called transesophageal from lat. Oesophagus. Ultrasound allows you to perform stress tests called stress echoes.

The patient using drugs or physical exercise the load is specially increased to record changes occurring in the work of the heart in this mode. This method of examination helps to identify hidden pathological phenomena that go unnoticed in a relatively calm state. Heart ultrasound is prescribed for:

  • signs of left-right ventricular failure;
  • the presence of pathological noises when listening;
  • IHD of a chronic or acute nature;
  • myocardial infarction;
  • heart rhythm disturbances;
  • septic conditions;
  • chest injuries;
  • chest pain of unknown origin;
  • thrombosis of the main deep veins;
  • treatment with antibiotics for cancer;
  • suspected aortic aneurysm.

There is a group of patients who complain of chronic headaches. This procedure is carried out in order to exclude pathological changes in the atrial septa, due to which microebola (blood clots) appear.

Although both diagnostic procedures described are important, sometimes there are nuances that doctors take into account before prescribing. In a critical situation, when the ambulance team is responding to a call, a cardiogram of the heart is taken. The device is located in the car, so in case of an accident, hypertensive crisis, suspected of myocardial infarction, it can be done at home or on the way to the hospital. An examination using an electrocardiograph in such a situation helps to assess the patient’s condition and provide the help you need At once.

When the crisis has passed, the patient is advised additional examination using ultrasound. You should not refuse this procedure. Modern equipment allows you to see the smallest disorders that cannot be detected only with the help of an electrocardiogram. If the cardiologist prescribes only an ultrasound, check whether other procedures should be used.

Some patients are prescribed 24-hour monitoring, that is, a small sensor is attached to the patient’s body, which records all indicators of heart function throughout the day. This method helps to see how the heart muscle works during the day during the patient’s everyday load. A regular electrocardiogram does not allow recording extrasystole, especially if it is an episodic phenomenon. Holter monitoring is performed when there are complaints of interruptions in cardiac function, myocardial ischemia, or tachycardia.

The study through the esophagus is abbreviated as TES (transesophageal pacing) and has been used by doctors for about 30 years. This diagnostic method differs in that a sterile electrode is inserted directly into the esophagus, closer to the heart.
