Special features of right bundle branch block in patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia

International Journal of Cardiology, 05/16/2012

Complete right bundle branch block (CRBBB) and iCRBBB are infrequent findings in arrhythmogenic right ventricular cardiomyopathy. Complete right bundle branch block is characterized by r'/s ratio<1. There are no significant T wave inversions≥V4. Incomplete right bundle branch block is characterized by ST segment elevation in right precordial leads but not by T wave inversions≥V4.
