Multicenter Study Comparative StudyDetection of left ventricular hypertrophy by different electrocardiographic criteria in clinical practice. Findings from the Sara study.
The objective of this study is to compare the validity of different product duration-based electrocardiographic criteria with the classical voltage criteria and to estimate the prevalence of left ventricular hypertrophy (LVH) for each criterion. Electro cardiographic criteria from 248 hypertensive patients attended in daily clinical practice were examined. Cornell and Sokolow-Lyon voltage indexes, Cornell and Sokolow-Lyon products, and Cornell and Sokolow-Lyon areas were determined. ⋯ The Cornell and Sokolow-Lyon product and the QRS area-based criteria improve the detection of ECG-LVH in the hypertensive population. The composite of different criteria may be a useful strategy to further increase the diagnostic ability of ECG. The combinations of the Cornell product with the Sokolow voltage or with the Sokolow product appear to be the most efficient options.
