Abstract:
Background: Echocardiography has provided the most valuable means in detecting Left Ventricular Hypertrophy (LVH), but electrocardiography (ECG) has a greater advantage due to its mobility, simplicity, and low cost. Objective: (1) To examine the sensitivity and specificity of electrocardiographic criteria for LVH and determinants. (2) To study the risk factors affected to sensitivity and specificity of electrocardiography. Subjects and method: ECG and echocardiography were performed in 374 adults. The Romhilt-Estes score was used to measure electrocardiographic LVH, whereas the Framingham criteria of the left ventricular mass index were used to detect LVH on echocardiography. Results: Using echocardiography as a gold standard, sensitivity of ECG was 35.8%, specificity was 90.3%. The overall probability of correct diagnosis was 82.6%. Older people and men had tended to increase the value of ECG in detecting LVH. Conclusion: The high specificity but low sensitivity suggested an adjusted ECG criterion for a better diagnosis of electrocardiographic LVH.
