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.
27 kwi 2018 · 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. Over the years, a variety of methods have been proposed for automatic analysis of PCG signals in time, frequency, and time-frequency domains.
17 lip 2023 · Heart sounds and murmurs have been described in terms of their timing in the cardiac cycle, intensity, how intensity changes during the cardiac cycle, sound wave shape, pitch, location where the sound is audible, radiation, rhythm, and response to physical exam maneuvers.
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 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.
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.
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.
