What is phonocardiographic?

Phonocardiography (PCG) is a technique used to record and analyze heart sounds and murmurs. It involves using a microphone or sensor to pick up the sounds of the heart as it beats and then converting those sounds into a visual representation, such as a graph or waveform. This allows healthcare practitioners to identify abnormalities in the heart's functions, such as valve problems or issues with blood flow, which can lead to a variety of cardiovascular diseases. Phonocardiography is commonly used in conjunction with echocardiography, electrocardiography, and other diagnostic tests to provide a more complete picture of a patient's cardiac health. It is non-invasive and usually painless, making it a safe and effective way to monitor the heart's functions over time.
