There are several criteria out there for left ventricular hypertrophy, and none of them are particularly sensitive. They’re all less than 50% sensitive, but they’re usually quite specific – 85 to 90%. The most cited criteria are the Sokolow-Lyon and the Cornell criteria, which consider voltage amplitude. There are also ST/T wave changes associated with LVH that may increase the specificity when seen. Namely, lateral ST depressions and asymmetric T wave inversions.
