Arrhythmogenic RV Dysplasia

Introduction to Clinical Electrophysiology and the ECG

This is an example of Arrhythmogenic RV Dysplasia heard at the tricuspid area. This is a familial abnormality which is associated with replacement of the right ventricle with fibro-fatty tissue. In this condition there is marked enlargement of the right ventricle with decreased vigor of contraction. The first and second heart sounds are normal. There is a pansystolic rectangular murmur caused by regurgitant turbulent flow from the right ventricle into the right ventricle.
