Accuracy of electrocardiography in diagnosis of left ventricular hypertrophy in arterial hypertension: systematic review.

ABSTRACT:

Objective

To review the accuracy of electrocardiography in screening for left ventricular hypertrophy in patients with hypertension.

Design

Systematic review of studies of test accuracy of six electrocardiographic indexes: the Sokolow-Lyon index, Cornell voltage index, Cornell product index, Gubner index, and Romhilt-Estes scores with thresholds for a positive test of > or =4 points or > or =5 points.

Data sources

Electronic databases ((Pre-)Medline, Embase), reference lists of relevant studies and previous reviews, and experts.

Study selection

Two reviewers scrutinised abstracts and examined potentially eligible studies. Studies comparing the electrocardiographic index with echocardiography in hypertensive patients and reporting sufficient data were included.<
