Correlation of Electrocardiography with Echocardiography of Left Ventricular Hypertrophy in Patients with Systemic Arterial Hypertension.
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 6
Abstract
Left ventricular hypertrophy is a unvarying predictor of adverse CV hazards. Electrocardiography is one of most routinely used methods for diagnosing left ventricular hypertrophy due to low cost and easy availability. Echocardiography has become gold standard for detection of left ventricular hypertrophy in last few decades but it is costlier than electrocardiography and less reproducible. Aims and objective To identify the left ventricular hypertrophy in hypertensive patients and to find the correlation between electrocardiography and echocardiography in left ventricular hypertrophy. Material and Methods This study was conducted at M.M.I.M.S.R, Mullana, Ambala. Fifty patients with hypertension were included in study after fulfilling inclusion and exclusion criteria. Patients were evaluated for LVH using ECG and echocardiography. Sokolow-Lyon and Cornell index criteria were applied to all subjects and their efficacy in detecting LVH was measured in comparison to echocardiography. Results Among 50 patients, 28 were male and 22 were female. Mean age was 48.72±9.719 years. Echocardiography detected left ventricular hypertrophy in 82% cases. In comparison to echocardiography, Sokolow- Lyon and Cornell criteria were specific for LVH (66.67%, 88.89% respectively) , but poorly sensitive (36.59%, 39.01%) respectively. Combining both these criteria, raised the sensitivity to 48.78%. Both the criteria showed moderate correlation with echocardiography by Pearson analysis. Conclusion Both Sokolow-Lyon and Cornell criteria are poor screening tools due to low sensitivity. Nevertheless, during routine evaluation of patients with hypertension, if any individual is positive by any ECG criteria ,that would need assessment by echocardiography.
