The ultrasound of the heart ultrasound is different from other agencies?
Typically, ultrasound of the heart is called echocardiography, while stressing the fact that it is carried out using a speci
What are the different types of ultrasound of the heart?
UZIv dimensional M-mode.The sensor produces an image in real time and resembles a top view of the heart.It allows you to calculate the linear dimensions of the chambers and valves, the lumen.It is used in infants, young children and adults.Washer, allowing to obtain a one-dimensional image, were widespread in the early days of echocardiography.
Two-dimensional ultrasound.It creates an image of the heart in two planes.Allows you to calculate the area of the openings of the mitral, aortic and tricuspid valves of the heart and great vessels lumen.
Three-dimensional (Doppler ultrasound) .Today the most frequently used, as it gives the most complete information about blood flow and heart anatomical spaces.With the help of modern means of modern programming devices can show three-dimensional image of the body in real time, which greatly facilitates the diagnosis of the problem.
What are the ways of the ultrasound of the heart and how to prepare them?
through the chest (transthoracic echocardiography) .In this case, the patient is laid bare to the waist, and falls on the medical couch, turning on your left side.This position is the most convenient for the study of the heart, because as much as possible closer to the tip of his chest.
Then the doctor lubricates the chest special gel to provide better contact with the sensor unit and begins to conduct a study.At this time, the picture appears on the monitor, which, depending on the type of ultrasound machine can be one-, two- and three-dimensional.
transthoracic ultrasound does not require special preparation of the patient.In many hospitals it is enough just to bring a sheet, which will be laid out medical couch, and a towel to remove the remnants of the gel applied to the skin after the end of the study.
This ultrasound is desirable to carry out at least once a year for those who have any heart disease, especially congenital or acquired defects.
Transesophageal ultrasound.Sometimes transthoracic echocardiography because of prosthetic valve abnormalities or chest structure is uninformative, then resorted to holding ultrasound through the esophagus.In such a situation, using a special sensor probe placed in the esophagus at the level of the left atrium.The patient thus also lies on its side, and the probe is processed gel tighter contact.
Transesophageal echocardiography requires special preparation of the patient: it is necessary to come to study on an empty stomach, without taking fluid or food for at least 4-6 hours prior to the ultrasound.Duration transesophageal ultrasound of the heart usually takes no more than 10-15 minutes.
Abdominal echocardiography.This method is ultrasound of the fetal heart.In this case, the sensor device is moved along the surface of the anterior abdominal wall of the pregnant woman, and carefully examine the structure of the heart muscle, identifying possible anomalies.
Preparation for this type of research is also not required, however, if the gestational age is not very large, it is necessary to make sure that the accumulated gases in the intestines of the orderly conduct of Echocardiography (for this purpose often a few days before the study is assigned to take activated charcoal orother sorbents).
echocardiogram with exercise or with medicines (stress echocardiography).On average, such a study lasting for 45 minutes at etomizuchayutsya heart chambers and their change during exercise.To this end, during the US appointed a special patient medication or dosage exercise.
Preparation for this type of study include the following:
- patient clothing should be loose, not tight and does not hinder movement.
- 2 hours before the start of the procedure is recommended to eat something and drink some water.
- For 3 hours should be discontinued in any physical activity.
What does the ultrasound of the heart
Explanation even three-dimensional ultrasound - a lot of Cardiology and ultrasound specialists.The fact that only a physician can correctly interpret the results and to establish causal relationships between the data obtained during the echocardiogram, the clinical picture of the disease and other types of surveys.
In general, using a heart ultrasound can detect the following abnormalities:
- mitral valve prolapse;
- anomalies of heart development;
- hypoplasia of the left ventricle ,;
main indications for echocardiography
Ekokardiografiya shows mandatory in the following situations:
- permanent presence of a heart murmur;
- pain in the chest;
- the signs of heart failure;
- occurrence of shortness of breath, fatigue during normal exertion;
- cyanosis of the fingertips, nasolabial triangle,
- during pregnancy.
ultrasound is necessarily part of the survey on the eve of cardiac surgery, as well as before the birth, if the infant is suspected pathological changes in the body, which may require emergency surgery immediately after birth.
With such inexpensive and available studies, as ultrasound, doctors were able to save thousands of lives and avoid many unnecessary surgical interventions.
