From this article you will learn: how is heart ultrasound performed( Echo KG), whether special preparation is needed for the procedure. Who is assigned this method of diagnosis, what he shows. Decoding of the results of ultrasound of the heart and norm.

Using ultrasound of the heart, one can thoroughly examine the structure of this organ and assess its ability to pump blood. With the help of Echo KG you can see the size of all the chambers of the heart, the thickness of the walls and partitions, the area of the valve holes and the diameter of the main vessels flowing from the heart, the rate of blood flow through the valves, the volume of blood ejected by the heart chambers.
With the help of this method, it is possible to diagnose organic heart defects, valve anomalies, cardiomyopathies, violations of contractility of the myocardium, diseases of large vessels departing from the heart( aorta, pulmonary trunk).
This research is assigned the main role in the diagnosis of cardiovascular pathologies, as it is very informative, safe for people of any age, absolutely painless, does not require long preparation of the patient.
Direction on ultrasound of the heart can be taken from a cardiologist. The procedure is performed by an expert in ultrasound.
Indications for
Echo CG are done for all patients with suspected heart disease.
Such people usually come to a cardiologist with complaints of severe palpitation, discomfort or chest pain, fatigue, swelling, dyspnea. These are typical symptoms of chronic heart failure.
Also on ultrasound can send a person who has found abnormalities on the ECG, even if there are no unpleasant symptoms.
Echocardiogram is desirable for prophylactic purposes:
- every 1-2 years for healthy children and young adults;
- once a year - athletes;
- every six months or a year people over 60;
- every 6 months to those who suffer from chronic cardiovascular diseases, and those who have small congenital heart defects that are asymptomatic;
- to all pregnant women( ultrasound of the mother's heart is necessary and, if there is evidence, an ultrasound of the fetal heart).
What diseases can be detected
Using Echo KG diagnose:
- hypertrophy or dilatation of the heart chambers;
- cardiomyopathy;
- stenosis of the aortic, tricuspid, mitral or pulmonary valve;
- failure of any valve;
- mitral valve prolapse;
- diseases of the thoracic aorta( stratification, aneurysm, hematoma, rupture);
- failure of the left ventricle or other parts of the heart;
- defect of interatrial or interventricular septum;
- heart thrombosis;
- pericarditis;
- The tetralogue of Fallot and other rare heart defects.
Preparation for
No special training is required.
There are only a few recommendations:
- One day before the procedure, do not drink alcohol, coffee, strong tea.
- On the day when you are doing ultrasound( or at least 2-3 hours before it), do not smoke.
- If you are taking any medications, tell the cardiologist who sent you to a heart ultrasound. Perhaps he will advise you to skip the medication on the day of the procedure.
- During the last 10 minutes before the examination, sit and relax.
With you, you will need to have a sheet to lay it on the couch, and a towel to wipe the remnants of the gel from the body. You can take one large towel, it will replace the sheet.
The procedure of
ultrasound is done in this way:
- You remove all clothing above your belt.
- Lie down on the couch on your back or on your left side.
- Doctor puts on chest special gel for ultrasound and leads to the body by a specific sensor.
- The image of the heart is displayed on the doctor's monitor, and he immediately records the data.
- The procedure lasts 10-15 minutes.
- When you are finished, you get up, wipe the skin off the gel remnants and dress.
- decipher the figures obtained may itself ultrasound specialist, but definitive diagnosis is a cardiologist who gave you directions.
Indicators echocardiography in normal
The table contains rules for adults. Deviations from the norm do not always indicate a disease and can be an individual feature of the body. Do not invent illness for yourself if your heart ultrasound readings do not fully correspond to the norm - a diagnosis can only be made by a cardiologist. If you are not sure of the diagnosis, consult another cardiologist.

Contraindications and complications
no contraindications. May be performed in infancy and in the elderly, pregnant, seriously ill.
Very rare phenomenon - an allergy to the gel for ultrasound. It can be expressed by itching and redness at the site of application. If you have had it, tell your doctor about it - you will need to buy a hypoallergenic gel yourself or you will be provided with it.
In any case, the local skin reaction to the gel is not dangerous and passes for several days.
