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.
Its application can be extended to other diseases, including LV hypertrophy, constrictive pericarditis, sleep apnea and ventricular fibrillation. The newly developed ambulatory acoustic cardiography is potentially used in heart failure follow-up in both home and hospital setting.
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.
Phonocardiography. 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.
3 paź 2017 · For this document, the writing group reviewed research published since 2004 to provide updated recommendations for indications, duration, and implementation indications for continuous electrocardiographic monitoring in hospitalized patients.
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].
