Abstract

The aim of the study was to find out sensitivity and specificity of different ECG criteria to detect left ventricular hypertrophy in males and females. All patients with age > 20 yrs with echocardiography proven LVH were selected for study group I (cases). A total number of 55 patients were enrolled into the study group II who did not have left ventricular hypertrophy in echocardiography. The study participants were considered clinically and echocardiographically normal if they were free of alterations in the cardiac chambers, valve changes of hemodynamic significance, a significant transvalvular gradient detected by colour flow doppler, had a systolic blood pressure below 140 mmHg and a diastolic blood pressure below 90 mmHg, had no abnormalities on clinical examination and were not using any medications. Result: A total no. of 100 patients was enrolled. Total no. of males was 71 and females were 29. Two study groups the first comprising of 45 subjects with LVH and the second comprising of 55 subjects without LVH were identified.Of the total no. of 45, patients 36 patients (80%) had LVH due to hypertension. Conclusion: In the present study 26.7% (n=12) of cases were females and 74.3% (n=33) were males. Male: female ratio was 2.7:1 among cases. Aetiology of 80% (n=36) patients with LVH was hypertension. 15% was due to valvular heart disease (n=7). Maximum sensitivity among the ECG criteria for LVH was shown by Romhilt Estes score > 4 (57%) followed by sokolow lyon product which showed 46% sensitivity. Maximum specificity was shown by Romhilt Estes score > 5(definite LVH) and Gubner ungirdlier criteria (98.1%).
