Rytand’s Murmur – Cardiology MCQ

Rytand’s Murmur is:

a) Mid diastolic murmur heard in complete heart block
b) Mid diastolic murmur heard in mitral stenosis
c) Mid diastolic murmur heard in aortic regurgitation
d) Mid diastolic murmur heard in tricuspid regurgitation

Correct answer: a) Mid diastolic murmur heard in complete heart block

When the atrial contraction coincides with the rapid filling phase of the ventricle, the turbulent flow across the mitral valve produces this functional (flow dependent) diastolic murmur.
