Phonocardiography : Diagnosis-Benefits-Types


 What Is Phonocardiography?

A phonocardiogram (or PCG) is a plot of high-fidelity recording of the sounds and murmurs made by way of the coronary heart with the help of the device called the phonocardiography thus, phonocardiography is the recording of all of the sounds made through the heart all through a cardiac cycle.

Phonocardiography, a diagnostic approach that creates a picture file, or phonocardiogram, of the sounds and murmurs produced through the contracting heart, which includes its valves and related awesome vessels. The phonocardiogram is obtained both with a chest microphone or with a miniature sensor within the tip of a small tubular instrument that is added via the blood vessels into one of the coronary heart chambers. The phonocardiogram generally dietary supplements the statistics obtained by means of being attentive to body sounds with a stethoscope (auscultation) and is of unique diagnostic value when finished concurrently with size of the electrical residences of the heart (electrocardiography) and pulse fee.

What Is Phonocardiography

Heart sounds end result from vibrations created with the aid of the closure of the heart valves. There are as a minimum ; the first (S1) is produced whilst the atrioventricular valves (tricuspid and mitral) close at the beginning of systole and the second (S2) when the aortic valve and pulmonary valve (semilunar valves) near on the end of systole.

Phonocardiography permits the detection of subaudible sounds and murmurs and makes a permanent file of those events. In comparison, the stethoscope can't constantly stumble on all such sounds or murmurs and provides no document of their occurrence. The potential to quantitate the sounds made by way of the coronary heart provides data not quite simply to be had from more sophisticated checks and provides critical statistics about the consequences of sure tablets on the coronary heart. It is likewise an effective approach for tracking the development of a patient's sickness.

What is the difference between ECG and PCG?

  • The electrocardiogram (ECG) and phonocardiogram (PCG) are two tests used to measure the electrical signals formed by the heart. The ECG is performed by placing electrodes on the chest and limbs of a patient to measure electrical signals on the surface of the skin. The signals are then sent to a computer to be analyzed. The PCG involves placing a microphone on the chest of a patient and recording the heart sounds generated by the heart valves.

  • Electrocardiography (ECG) and phonocardiography (PCG) are two methods used to measure and diagnose cardiac activity. ECG is a non-invasive technique that uses electrodes placed on the skin to measure electrical impulses generated by the heart. PCG is an invasive technique that uses microphones placed near the heart to record sounds generated by the heart. ECG provides more detailed information on the electrical activity of the heart, while PCG provides more detailed information on the mechanical activity of the heart.

  • ECG, or Electrocardiography, is a medical procedure used to measure the electrical activity of the heart. PCG, or Phonocardiography, is a similar procedure that measures the sound made by the heart.  The main difference between the two is the type of signal being measured; ECG measures the electrical activity of the heart, while PCG measures the sound waves produced by the heart. Both procedures use electrodes and sensors to record data, but ECG is more accurate as it records electrical signals more precisely.
