Abstract

The venous hum, a continuous murmur usually of maximum intensity in the supraclavicular area, is a common auscultatory finding. Heard particularly in children, it is of no known pathological significance. Its importance lies rather in its often close resemblance, because of its continuous or predominantly diastolic characteristic, to pathological murmurs. Our interest in the venous hum stems from the observation of numerous patients in the cardiology and pediatric clinics of the Medical College of South Carolina, in whom the murmur was transmitted down to various areas of the precordium where its presence was of concern in auscultation.

In this presentation the clinical features of venous hum are discussed as they pertain to cardiac auscultation. Emphasis is placed on procedures that permit the differentiation of this murmur from murmurs of pathological significance on the basis of clinical findings alone.

Most present-day textbooks of cardiology and pediatrics give brief, if any, mention
