Abstract

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.
