Description

Rytand murmur: Mid-late blowing diastolic murmur heard occasionally in patients with complete atrioventricular heart block. Best heard at the apex, and often confused with mitral stenosis (no opening snap).

A blowing diastolic murmur heard occasionally in patients with complete atrioventricular heart block. Best heard at the apex and often confused with mitral stenosis, the murmur is loudest when it appears early in diastole (i.e. when it coincides with the end of the early rapid filling period of the ventricle) but may appear anytime during diastole.


History of the Rytand murmur

Rytand was not the first to identify the presence of a diastolic murmur in patients with atrioventricular block without mitral stenosis, with Wolferth and Margolies describing its existence in 1930, and Stead and Kunkel describing it in 1939.

Rytand was, however, the first person to describe and characterise the murmur in detail.

Observations are reported on a blowing apical murmur related to auricular activity in nine elderly but ambulatory patients with varying degrees of auriculoventricular block.

…another murmur which may be heard at the cardiac apex during diastole in the absence of mitral stenosis.
