Left Ventricular Hypertrophy - LVH

Left Ventricular Hypertrophy

  • Wide QRS in lead I
  • Narrow QRS in V6
  • Increased R wave in left sided leads (I, aVL, V5-V6)
  • Increased S wave in right sided leads (III, aVR, V1-v2)

Voltage Criteria:

Precordial Leads

  • R wave in V5 or V6 + S wave in V1 > 35 mm

Non-Voltage Criteria

Left ventricular Strain Pattern: ST segment depressioon and T wave inversion in the left-sided leads (leads I, AVL, V5, V6, occasionally inferior leads)

LVH by voltage criteria: S wave in V2 + R wave in V5 > 35 mm
