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).

Si multaneous high frequency (HF) phonocardiograms from the pulmonary (PA) and mitral (MA) areas, indirect carotid pulse tracing (CAR) and electrocardiogram. During inspiration, the second sound (2) in the pulmonary area is split by 0.04 second, becoming single on expiration.
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.
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.
Phonocardiograms are visual representations of heart sounds that have been used for diagnosis [4, 5] and have been advanced as a curricular approach to teach students the typical shape, timing, and duration of heart murmurs that correspond to specific disease processes [6, 7].
12 sty 2021 · Initial investigations using phonocardiography as a curricular tool showed improvements in students’ ability to distinguish innocent from abnormal heart murmurs and resident and attending physicians’ ability to recognize diastolic gallops (e.g., S3 and S4) and to accurately identify underlying diagnoses .
12 cze 2016 · Phonocardiography is a diagnostic technique that graphically records cardiac acoustic phenomena. 10 Visualization of heart sounds may help in understanding cardiac events (Fig. 2–1). A visual record may also help an inexperienced listener recognize and classify auscultatory findings.
