Clues to the diagnosis of right ventricular hypertrophy
Clues to the diagnosis of right ventricular hypertrophy include the following:

- R/S ratio in V1 greater than 1
- S/R ratio in V6 greater than1
- Late intrinsicoid deflection in V1 (greater than 0.035 seconds)
- Incomplete right bundle branch block
- ST-T wave abnormalities (“strain”) in inferior leads
