Noise

Murmur (Murmur, Bruit) is a noise heard through a stethoscope, resulting from the presence of turbulent blood flow inside the heart or blood vessels. This murmur may be associated with valve damage, septal defects, narrowing of the arteries, or the formation of arteriovenous junctions. A heart murmur can sometimes be observed in completely healthy people with hyperactive blood circulation, as well as in children (functional murmurs).

Heart murmurs are divided into:

1. Systolic - audible during ventricular systole
2. Diastolic - audible during ventricular diastole
3. Continuous murmurs - heard both during systole and diastole

A heart murmur is a murmur that can be heard through a stethoscope. These murmurs occur as a result of turbulence in the blood flow inside the heart. Murmurs can be associated with various conditions such as valve damage, septal defects, narrowing of arteries, and arteriovenous junction formation.

A heart murmur may be associated with certain medical conditions, such as heart failure, arrhythmia, or congenital heart defects. However, some heart murmurs can be caused by other causes, such as overactive circulation or function murmurs.

Listening to a heart murmur is an important diagnostic tool that can help determine the presence of certain diseases or conditions. However, it must be remembered that a heart murmur is not always a sign of disease and can be caused by physiological reasons.

It is important to remember that heart murmurs are only one symptom, and additional research and consultation with a doctor are necessary to determine an accurate diagnosis.

Noise is a pulsation heard through a stetophone that occurs as blood passes through the blood vessels of the heart. The blood flow here is turbulent, that is, unsteady. Normally, we do not hear this, but when there are health problems or organs are working chaotically, this noise can be heard. In English-language literature it is called the term “Murmur” (“loud noise”).

This murmur can be divided into 2 categories: + Systolic murmur: occurs when the heart muscle contracts. In this case, the sound appears in phase I or at the end of phase II. The knock is uneven - short and dull; + Diastolic murmurs: occur before ejection of blood and during the interventricular pause. Accompanied by a dull sound signal with clicks. Since diastole is twice as long as systole, the murmur between beats may last longer. Noise occurs both in case of loss of closure of the partitions and due to their insufficient opening. The duration can suggest its intensity. If it lasts more than a second, then it is already a pathology.

Many diseases of the cardiovascular system are associated with noise and are directly related to fluctuations in blood flow in the vessels and arteries. The cause is often defects in the septum between the ventricles, valve regulators of blood flow, and vascular spasms. Murmurs can also occur at another stage of development, for example, during fusion of the main arteries.

Noise is classified into categories depending on its nature and frequency of repetition: - Constant - noise that is heard constantly during diastole and systole; - Systolic (systolice) - murmur at peak systole (point A2); - Diastolicexia (diasfoldie) - noise at the end of diastole (points IV and V). This type of murmur is usually associated with certain birth defects, such as coarctation of the aorta. - Presystolic - appears shortly before the onset of systole with reverse outflow of blood from the left atrium.
