A phonocardiogram is a recording of the sounds made by the heart with a phonocardiograph. Learn about its history, medical use, fetal application, and related terms.
Phonocardiography is the graphic representation of heart sounds and murmurs using a microphone-transducer or an electronic stethoscope. Learn about the history, application, and analysis of phonocardiograms in medicine and dentistry, and explore related chapters and articles.
Phonocardiography is a technique that records the sounds and murmurs of the heart with a microphone or a sensor. It can supplement auscultation and electrocardiography in diagnosing heart conditions.
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.
Learn how phonocardiography can help diagnose congenital and acquired heart disease by recording and analyzing heart sounds and murmurs. The article explains the basic principles, methods and applications of phonocardiography with examples and illustrations.
For a reliable and accurate diagnosis, physicians require more information to correlate the temporal relationships between the heart sounds, the atrial and ventricular BP waveforms (mechanical events), and the ECG signal ( electrical events) during the cardiac cycle.
Learn about phonocardiography, the detection and recording of heart sounds, from various chapters and articles on ScienceDirect. Find out how phonocardiography is used in cardiovascular techniques, cardiac pacing, defibrillation, and resynchronization therapy.
