phonocardiography

 [fo″no-kahr″de-og´rah-fe]
the graphic recording of heart sounds and murmurs; by extension, the term includes pulse tracings (carotid, apex, and venous pulse). adj., adj phonocardiograph´ic.

Phonocardiography involves picking up, through a highly sensitive microphone, sonic vibrations from the heart which are then converted into electrical energy and fed into a galvanometer, where they are recorded on paper. The procedure is most useful when there is evidence of heart murmurs or unusual heart sounds, such as gallops, that are difficult to discern by the human ear.

1. Recording of the heart sounds with a phonocardiograph.
2. The science of interpreting phonocardiograms.
[phono- + G. kardia, heart, + graphō, to record]

phonocardiography

Echophonocardiography Cardiology A non-invasive technique that amplifies faint, low frequency sounds of blood flowing through the heart and great vessels, displaying them graphically; PCG encompasses carotid, apex, and venous pulse tracings Applications Diagnose heart valve defects, ventricular hypertrophy, left heart failure; PCG is usually performed in synchrony with EKG, and M-mode echocadiography or Doppler echocardiography, to match changes heard by PCG with the point at which they occur in the heart beat

Phonocardiography involves picking up, through a highly sensitive microphone, sonic vibrations from the heart which are then converted into electrical energy and fed into a galvanometer, where they are recorded on paper. The procedure is most useful when there is evidence of heart murmurs or unusual heart sounds, such as gallops, that are difficult to discern by the human ear. Most recordings are made through an externally applied microphone but intracardiac recordings, made through a phonocatheter, are possible.
