Phonocardiography in Clinical Practice

Abstract

A special direct-writing phonocardiograph was used in a study of more than 300 patients who were referred to a consultation service because of unusual or perplexing auscultatory findings. The tracings accurately demonstrated time relationships and other features of murmurs and sounds which often cannot be ascertained by auscultation. Results of the study indicate that phonocardiography should be more widely applied in clinical practice. The availability of a simple, convenient, direct-writing instrument should make this practical.
