Clues to the diagnosis of right ventricular hypertrophy


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


[A] R/S ratio in V1 greater than 1
[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:

  1. Right axis deviation (greater than 90)
  2. R in V1 greater than 6 mm
  3. R in V1 + S in V5 or V6 greater than 10.5 mm
  4. R/S ratio in V1 greater than 1
  5. S/R ratio in V6 greater than1
  6. Late intrinsicoid deflection in V1 (greater than 0.035 seconds)
  7. Incomplete right bundle branch block
  8. ST-T wave abnormalities (“strain”) in inferior leads
  9. Right atrial hypertrophy/overload (“P pulmonale”)
  10. S greater than R in leads I, II, III, particularly in children (S1S2S3 pattern)
