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.
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.
Phonocardiogram was developed in an attempt to provide quantitative and qualitative information of heart sounds and murmurs. The phonocardiogram records heart sound through a microphone, which is placed on the chest wall of subjects.
12 maj 2021 · A phonocardiogram (PCG) is a special sound waveform that plots in high fidelity the intensity of heart sounds over time. The two fundamental heart sounds, called "S1" and "S2", are shown on a PCG as large magnitude deflections occurring one after the other, with S1 first.
6 mar 2023 · A phonocardiogram (PCG) is a graphic representation of the sounds produced by the heart during the cardiac cycle. It is a non-invasive diagnostic tool that records the acoustic signals generated...
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.
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].
