What is hypertrophic cardiomyopathy?

Hypertrophic cardiomyopathy occurs when the cells in heart muscle enlarge and cause the walls of the ventricle (normally the left ventricle) to thicken. It can be diagnosed at any age and is more common in men than in women. For more information on hypertrophic cardiomyopathy, please see Additional Information, below.

Pulse point

There are a number of different formulae for diagnosing LVH via ECG. One of these is the Sokolow-Lyon formula:

  • S in V1 or V2 R in V5 or V6 (whichever it is the larger) ≥ 35mm (≥ 7 large squares)
  • R in aVL ≥ 11mm
