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.
1 wrz 2023 · The paper presents evaluation of the proposed phonocardiography (PCG) measurement system designed primarily for heartbeat detection to estimate heart rate (HR).
Phonocardiography is a diagnostic technique that graphically records cardiac acoustic phenomena. 10 Visualization of heart sounds may help in understanding cardiac events . A visual record may also help an inexperienced listener recognize and classify auscultatory findings.
27 kwi 2018 · The mechanical activity of heart due to its physical movement produces four distinct sounds or beats which are named as first normal heart sound (S1), second normal heart sound (S2), third abnormal heart sound (S3), and fourth abnormal heart sound (S4).

A phonocardiogram (PCG) plots recordings of a heart sound and murmur during the cardiac cycle, and analysis of a PCG signal is useful in detecting abnormalities of a heart by using time-frequency analysis and classifications of the heart signals (Milani, Emeroylariffion, Silva, & Nanayakkara, 2021).
The phonocardiogram and simultaneous indirect carotid pulse tracing are extremely helpful in the differentiation of a late pulmonary valve closure from an opening snap and ventricular diastolic gallop.
