sensitivity for LVH detection, LVH diagnosed by the Sokolow-Lyon index or the Cornell voltage-duration product is an independent predictor of cardiovascular events both at baseline and during antihypertensive treatment (1). The predictive power of voltage criteria for ECG-LVH is not evident in obese patients (4).

Neither of the combination voltage criteria was able to differentiate between the two types of echo LVH. Table 1. Sensitivities of various ECG voltage …

Currently accepted LVH ECG criteria such as Cornell voltage and Sokolow-Lyon were used for comparison. The validation cohort consisted of 122 consecutive patients referred for an echocardiogram regardless of the admitting diagnosis. RESULTS The S D was the most accurate single lead measurement for the diagnosis of LVH (AUC: 0.80; p < 0.001).

Thus, Sokolow-Lyon voltage criteria underestimate the prevalence of anatomic LVH in the presence of obesity, whereas Cornell product criteria for ECG LVH appear to provide a more accurate measure of LVH in obese and overweight patients.
