Abstract:

Introduction: Electrocardiography (ECG) is relatively insensitive and cannot accurately quantitative the severity of left ventricular hypertrophy (LVH). Echocardiography has revolutionized the diagnosis of LVH because echocardiographic evidence of LVH occurs in 30 to 40 percent of hypertensive patients whose ECG and chest X-ray are normal. Keeping in view the importance of detecting LVH in cases of hypertension, this study is conducted to see the correlation of electrocardiographic diagnosis of LVH with echocardiography among the local population in cases of hypertension.

Materials and Methods: About 30 males and females of age 38 – 74 years, having longstanding hypertension, where LVH is suspected were included in the study and ECG and echocardiography was done on the same day.

Results: 22 (73.34%) were found to have LVH on echocardiography. 16 (53.34%) were found LVH on Electrocardiographically out of 30 patients. 22 (73.34) were in stage II hypertension and patients in stage I were 8 (26.67%). 2 (25%) had LVH on ECG alone and 4 (50%) had left ventricular hypertrophy on echocardiography alone. 7/16 (43.75%) patients had left ventricular hypertrophy on electrocardiography and 15/16 had left ventricular hypertrophy on echocardiography (93.75%) (p<0.05). Only 7/16 patients had LV H on both ECG and ECHO. Conclusion: echocardiography is more sensitive and offers a greater precision for detecting left ventricular hypertrophy especially when interventricular septum and posterior wall thickness measurements are taken into account. To make the left ventricular hypertrophy more specific on echocardiography, the left ventricular mass measurement is a better diagnostic tool.

Key words: Echocardiography, Electrocardiography (ECG), Left ventricular hypertrophy (LVH) and hypertension.
