[B] R in V1 + S in V5 or V6 greater than 10.5 mm
[C] S/R ratio in V6 greater than1
[D] Early intrinsicoid deflection in V1
Clues to the diagnosis of right ventricular hypertrophy
Clues to the diagnosis of right ventricular hypertrophy include the following:
- Right axis deviation (greater than 90)
- R in V1 greater than 6 mm
- R in V1 + S in V5 or V6 greater than 10.5 mm
- 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
- Right atrial hypertrophy/overload (“P pulmonale”)
- S greater than R in leads I, II, III, particularly in children (S1S2S3 pattern)
