Points of auscultation of the heart: rules and features of listening to the "engine"

One of the most orthodox and reliable methods of examining internal organs is auscultation. This reliable method is based on listening to the noise in the organs and related to their activities. In total there are five points of auscultation of the heart.

General information

Heart auscultation is direct or direct, as well as indirect( indirect).In order to conduct auscultation of the heart correctly, you need to adhere to certain recommendations.

Basic rules of

The key rules of auscultation of the heart are few. Every specialist in medicine must know them. The rules are as follows:

1. The room in which the heart is auscultated should be warm, well lit and quiet.
2. The researcher, if he is healthy, should be in a horizontal position( when the person is seriously ill, the procedure is carried out lying down).
3. The surface of the skin should be carefully prepared for examination( the effect of the stethoscope is not permissible where there is hair).
4. The device must be firmly pressed against the skin of the subject.

In accordance with the task, a specialist can change the position of the patient's body.

It is important to pay attention to the patient's breathing regulation. In some cases, the specialist offers him a little cough.

Key points of

Five points of auscultation of the heart should be distinguished:

• the first is the zone of apical cardiac shock( intended for listening to the mitral valve);
• the second is in the second intercostal space, next to the right edge of the sternum( on the aorta);
• the third is located in the second intercostal space, next to the left edge of the sternum( on the pulmonary artery);
• the fourth heart auscultation point is in the attachment zone to the sternum of the xiphoid element( right edge);
• the fifth heart auscultation point is located in the intersection zone connecting the first and second points of the line.

Features of the listening procedure

In some cases, the noise of the human "engine" changes greatly after a significant physical load. Therefore, the technique of auscultation of the heart suggests that the doctor can offer the patient:

1. Perform several sit-ups.
2. Several staircases come up.
3. Several times to bypass the doctor's office or ward.

Physical activity is only due to the fact that the patient is not in serious condition.

Exercise allows you to detect important changes in the noise of the human "engine", which contributes to the correct diagnosis.

General recommendations

It is important to remember that the heart should not be dried in a hurry. Otherwise, the expert is unlikely to receive correct information, and the auscultative picture will be highly distorted.

At the same time, it is important to consider that too long a procedure leads to blunting of hearing associated with fatigue. In this regard, listening efficiency can also decrease.

The best option is a moderate listening, which implies observing the necessary pauses. This helps to get the necessary effect to the specialist.

Noises

If auscultation of the heart is carried out in relation to a sick person, then a specialist can detect not only heart sounds, but also specific sound phenomena - the so-called noise.

These noises are formed against the background of narrowing of the hole.blood-letting. Also, their appearance is justified by an increase in the rate of blood flow. In addition, these sound phenomena are caused by the reduction of blood viscosity or the increase in heart rate.

Cardiac noises are:

• intracardiac( formed within the human "engine");
• are non-cardiac( formed outside the human "engine").

Listening stages

According to the auscultation of the heart method, the first stage of heart listening involves an analytical approach. In this case, the auscultative symptomatology should be divided by a specialist into several actual fragments.

First the doctor focuses on heart tones. This is relevant for both the first and the second stage. Then the systolic component attracts the doctor's attention. The last important element should be considered diastolic pauses.

An integrated assessment of the functioning of the main human organ can be obtained only on the basis of data collected through listening.
