Abstract
Aims: To assess the validity of the electrocardiogram (ECG) as a diagnostic tool for left ventricular hypertrophy (LVH) for different ethnic groups with echocardiography as a standard.
Methods: Systematic review of the literature using the Cornell and Sokolow-Lyon voltage criteria for LVH.
Results: Five studies were identified. Pooled data from these studies demonstrated low sensitivity using both types of ECG criteria for white and African-origin groups, but with slightly higher sensitivity values for the African-origin group (Cornell, 31.2%; 95% confidence interval [CI], 28%-34.8%; Sokolow-Lyon, 32.9%; 95% CI, 29.5%-36.4%) compared with the white group (Cornell, 26.5%; 95% CI, ...
