Background and Aim: Left ventricular hypertrophy (LVH) marks the ongoing disease process involving the heart. A precise diagnostic tool needs to be established to accurately determine LVH by electrocardiography (ECG), which itself is a predictor of future cardiovascular mortality and morbidity. Assessment of LVH electrocardiographically by Sokolow-Lyon voltage criteria and Cornell voltage criteria in obese individuals. Methods: Obese 50 individuals with LVH secondary to hypertension confirmed by echocardiogram were considered as study subjects. Standard 12-lead ECG was obtained and analyzed for Sokolow-Lyon voltage criteria and Cornell voltage criteria. Statistical analysis was done by unpaired t-test using SPSS package version 20. Results: According to Sokolow-Lyon voltage criteria, 42 cases (38.27 ± 2.96) and 41 controls (37.23 ± 2.01) had LVH which was statistically nonsignificant. According to Cornell voltage criteria, 36 male cases (35.42 ± 2.98) and 36 controls (32.3 ± 2.13) had LVH and it was statistically significant (P < 0.000 1). Ten female cases (26.87 ± 2.01) and 7 controls (22.9 ± 2.36) also had LVH and it was statistically significant (P < 0.002). About 84% of cases were assessed to have LVH by Sokolow-Lyon voltage criteria whereas 92% of cases were assessed to have LVH by Cornell voltage criteria. Conclusion: QRS duration is an independent ECG predictor of the presence of LVH. The Cornell voltage criteria significantly improve identification of LVH relative to Sokolow-Lyon voltage criteria in obese individuals.
