Question: what is left ventricular hypertrophy by voltage criteria?
Answer: Left Ventricular Hypertrophy ECG Criteria Modified Cornell Criteria: Examine the R wave in aVL. If the R wave is greater than 12 mm in amplitude, LVH is present. Sokolow-Lyon Criteria: Add the S wave in V1 plus the R wave in V5 or V6. If the sum is greater than 35 mm, LVH is present.
