Right bundle branch block and right ventricular hypertrophy
The electrical diagnosis of right ventricular hypertrophy is difficult in the presence of a right bundle branch block and is expressed only if the hypertrophy is anatomically significant.
In the presence of a complete right bundle branch block, the following signs are typical for hypertrophy:
- A high amplitude R' wave exceeding 15 mm in V1
- A very wide S wave in lead I
- A significant delay in intrinsicoid deflection in the right precordial leads
These various parameters are observed in this patient, with right ventricular hypertrophy frequently occurring in patients with chronic cor pulmonale.
