1. Definition

The ECG reflects high voltage criteria as extremely elevated QRS complexes, especially R-wave in the limb and precordial leads. If the ECG shows high voltage criteria, it could be a sign of ventricular hypertrophy. The opposite is low voltage.

2. Voltage criteria

For left ventricular hypertrophy (LVH):

  • Sokolow index: R wave in V5 + S wave in V1 = > 35mm
  • Lyon index: R wave in lead I + S wave in lead III = > 25mm
