Diagnostic Efficacy of Electrocardiography in Determining Left Ventricular Hypertrophy in Patients with Essential Hypertension

Abstract

A total of 37 hypertensive patients of both sexes over 18 years of age and more than four years of duration after diagnosis and only those having evidence of left ventricular hypertrophy (LVH) by echocardiography (ECHO) were enrolled to analyze the diagnostic efficacy of electrocardiography in determining left ventricular hypertrophy in patients with essential hypertension. Electrocardiograhpy (ECG) of 37 LVH diagnosed cases were analysed and 31 of them were found to have LVH on voltage criteria. Thus, the sensitivity of ECG in diagnosing LVH is 83%. Key Words: Left Ventricular Hypertrophy (LVH), Electrocardiography (ECG), Echocardiography (ECHO).
