ELECTROCARDIOGRAM AND ECHOCARDIOGRAPHIC STUDY OF LEFT VENTRICULAR HYPERTROPHY IN PATIENTS WITH HYPERTENSION

Abstract

Background: Hypertrophy of Left ventricle (LVH), secondary diastolic dysfunction of left ventricle, and left atrial dilatation are among the clinical indicators of hypertensive heart disease. Present study was aimed to study electrocardiogram and echocardiographic findings of left ventricular hypertrophy in patients with hypertension. Material and Methods: Present study was single-center, Cross-sectional study, conducted in patients of age more than 18 years, hypertensive patients newly diagnosed as per joint national committee guidelines or old cases on treatment underwent evaluation by ECG & 2DECHO. Results: There was significant difference in age distribution between the groups (P<0.05). There was no significant difference was found in gender distribution, presenting complaints, history of smoking & family history of HTN between the groups. There was significant association between duration of HTN and LVH. There was significant association between abnormal CVS examination, presence of clinical LVH, Sokolow and Lyon Voltage Criteria on ECG, Romhilt-Estes Point Score on ECG, Total QRS Voltage Criteria on ECG, Cornell Voltage on ECG, drug compliance and presence of LVH on 2D echo. On combining the ECG-SL and RE criteria’s, it was found that the sensitivity was 84.7% and specificity was 55.2%. LVH on 2D echo with significantly higher age in the group with LVH on 2D echo (63.52 ± 10.455 v/s 52.35 ± 9.803 years) compared to those without 2D echo. There was significant difference in mean duration of HTN between the groups with and without LVH on 2D echo with significantly higher duration of HTN in the group with LVH on 2D echo (13.36 ± 6.980 v/s 4.33 ± 2.773 years).
