Vinogradov-Durozier Double Noise

Vinogradov-Durozier double noise

A Vinogradov-Durozier double murmur is an additional heart sound that can be heard during cardiac auscultation. It is named after the Soviet therapist V.N. Vinogradov and the French doctor P.L. Duroziez, who first described this phenomenon.

The double Vinogradov-Durozier murmur is usually heard during ventricular systole, immediately after the first heart sound. It is caused by asynchronous contraction of the muscles of the heart wall and appears due to the difference in the time of contraction of various fibers of the ventricular myocardium.

This additional tone is more common in athletes, as they experience physiological myocardial hypertrophy. Also, double murmur can appear in some pathological conditions, for example, in hypertrophic cardiomyopathy. However, in most cases, this phenomenon does not carry any pathological significance and is regarded as a variant of the norm.



Vinogradov-Durozier, or double noise, is a set of noises that arise as a result of the merging of vibrations of two sound waves. This term is used in medicine to describe the phenomenon in which sounds produced by two organs are perceived as one single sound. This is a phenomenon
