Techniques for phonocardiogram signal analysis and efficiency assessment

Almustafa Khaled

The vibrations produced by the heart valves closing cause cardiac sounds. There are at least two: the first occurs when the tricuspid and mitral atrioventricular valves close at the start of systole, and the second occurs when the aortic and pulmonary valve semilunar valves close at the end of systole. Phonocardiography is a technique for detecting and recording sub audible sounds and murmurs in the heart. The stethoscope, on the other hand, does not always catch all of these noises or murmurs and does not keep track of their recurrence. The capacity to quantify the noises emitted by the heart provides information not available through more advanced tests and is crucial for understanding the effects of particular medicines on the heart.

It's also a good way to keep track of how a patient's condition is progressing. The primary function of a stethoscope is to perform a primary test to ensure the health of the heart. The people with abnormal heart beats need to be sent to cardio logical clinics. Today's medical technology is geared on cost savings, reduced diagnostic costs, and the preservation of human health. As a result, we require cutting-edge stethoscopes. When faced with specific conditions, adding the ability to diagnose heart aberrant sounds and providing the essential information about heart function may assist professionals to make smart decisions. We've seen attempts in recent years to identify problems just by listening to the heart and capturing the noises it makes
