Abstract              Background: Electrocardiographic evidence of left ventricular hypertrophy is one of the most widely used markers of cardiovascular morbidity. Inspite of their high specificity, the ECG indices are still less sensitive. Echocardiography has many advantages over electrocardiogram but it is expensive and not widely available in the rural regions of India. So, the study aimed to explore the correlation between ECG findings and echocardiographically detected left ventricular diastolic dysfunction. Material and Methods: Fifty clinically diagnosed patients of LVH were included in this study. The ECGs of patients enrolled in the study were scrutinized for evidence of left ventricular hypertrophy (LVH) by the Romhilt Estes Point Score system as well as Sokolow-Lyon Index. This was followed by echocardiography and left ventricular mass and left ventricular mass index was calculated. Results: The average age of a patient with left ventricular diastolic dysfunction was 59.66 years. Two patients had ECGs with evidence of LVH by the Romhit-Estes Point Score System and Sokolow-Lyon Index. Both patients with left ventricular hypertrophy on ECG had left ventricular diastolic dysfunction on echocardiography. Conclusion: ECG showed a low correlation with the echocardiogram however, sensitivity of ECG to detect LVH can be increased by Sokolw Lyons voltage criteria and Romhilt-Estes point score system.
