Phonocardiogram

A phonocardiogram is a recording of the sounds produced by the heart. These sounds are called heart sounds and murmurs. A phonocardiogram allows these sounds to be recorded and analyzed to diagnose various cardiovascular diseases.

A phonocardiogram is obtained using a special device - a phonocardiograph. The phonocardiograph sensor is installed on the chest in the area of ​​the heart and picks up sounds, which are amplified and converted into a graphic image - a phonocardiogram.

Analysis of the phonocardiogram allows one to evaluate the heart rate, the rhythm of the heart, the presence and characteristics of cardiac murmurs. A normal phonocardiogram has clear peaks of heart sounds without additional noise. Deviations from the norm may indicate various diseases of the valves, heart muscles or other disorders.

Phonocardiography is widely used in cardiology for diagnosing and monitoring the state of the cardiovascular system.

A phonocardiogram is a graphic representation of the sound signals that occur during the functioning of the human heart. It is used to diagnose heart diseases and evaluate the condition of the heart. A phonocardiogram is obtained using a special device - a phonocardiograph - which records sound signals on a paper tape or disk.

In this article we will look at the basic principles of phonocardiography and how it is used in medical diagnostics.

**How ​​does a phonocardiograph work?**

As the heart pumps, various sound waves occur, which can be heard using a special device - a phonocardiogram. These sound signals are recorded by a phonocardiograph and then displayed on paper or disk in the form of graphs.

A microphone is used to record sound signals and is placed near the patient's heart. The microphone picks up sound waves and transmits
