The Murmur of Peripheral Arteriovenous Fistula

Abstract

THE detection of a continuous murmur with systolic accentuation is of the highest significance in the diagnosis and in the location of the site of an arteriovenous fistula. It is therefore appropriate to emphasize certain characteristics of the murmur that may increase its usefulness as a physical sign. The study of patients with arteriovenous fistula by auscultation has been supplemented by visual registration of the murmurs through the use of a microphone connected to the phonocardiographic channel of a multiple-channel electrocardiograph. Several phonoangiograms thus obtained are reproduced in this report. Simultaneous tracings of the pulse wave or the electrocardiogram are . . .
