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).
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.
Cardiac auscultation in health and disease is an art in which competence is acquired with experience and effort. Careful study at the bedside and a careful interpretation of auscultatory findings by phonocardiography may provide a clinical diagnosis in most patients with congenital and acquired heart disease.
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.
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.
17 lip 2023 · The digital age has spawned the creation of phonocardiography, which is the use of a phonocardiogram to record sounds made by the blood and heart. One example of these is commercially available electronic stethoscopes. Their main features are their ambient noise canceling technology, and the ability to filter out and amplify specific noises.
