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.
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).
Cardiac auscultation is an important and basic component of a physical examination in clinical practice. For the experienced listener, auscultation provides quick and reliable diagnostic information about the state of the heart. Phonocardiography systems allow the listener to record these findings.
Phonocardiography, diagnostic technique that creates a graphic record, or phonocardiogram, of the sounds and murmurs produced by the contracting heart, including its valves and associated great vessels.
14 sie 2024 · The phonocardiogram (PCG) is routinely used for CVD detection, monitoring, and diagnosis. It is non-invasive, cost-effective, and sensitive to subtle changes that enhance the availability, capability, and sensitivity in abnormality detection.
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.
