What does a phonocardiogram measure?

What does a phonocardiogram measure?

The phonocardiogram (PCG) detects and records heart sounds, the sounds made by the various cardiac structures pulsing and moving blood. The sound is caused by the acceleration and deceleration of blood and turbulence developed during rapid blood flow.

What is phonocardiogram signal?

Phonocardiogram (PCG) signal represents recording of sounds and murmurs resulting from heart auscultation. Analysis of these PCG signals is critical in diagnosis of different heart diseases.

Which transducer is used for phonocardiogram?

Contact transducers (accelerometers) and air-coupled transducers are used.

Who invented phonocardiogram?

The phonocardiogram originated from Robert Hooke (1635-1703) who is credited with developing the idea, but equipment for the phonocardiogram was not developed until the 1930s.

What is PCG echocardiography?

89.55. A phonocardiogram (or PCG) is a plot of high-fidelity recording of the sounds and murmurs made by the heart with the help of the machine called the phonocardiograph; thus, phonocardiography is the recording of all the sounds made by the heart during a cardiac cycle.

What is PCG electrocardiography?

Besides an ECG signal, a phonocardiogram (PCG) signal is also employed for heart disease diagnosis. 17–21 In such a case, a PCG signal is the recorded heart sound using a microphone placed on the chest.

What is cardiac scintigraphy?

The Myocardial Scintigraphy examines the blood flow to the heart muscle at rest and during exercise without surgical intervention. Usually, there are two appointments necessary on two separate days. The stress test is used for diagnosis of circulatory disorders.

What is BCG and ECG?

While ECG measures cardiac electrical activity, a ballistocardiography (BCG) foil registers the mechanical vibrations caused by cardiac activity.
