Study of Dilated Cardiomyopathy in Correlation with Electrocardiography and Echocardiography in Patients less than 40 Years Age

Abstract

Background: DCM is a disease of the heart muscle, primarily affecting the left ventricle and characterized by ventricular dilatation, impaired systolic function, and reduced myocardial contractility. The present study was conducted to study the electrocardiographic and echocardiographic findings in patients with dilated cardiomyopathy in patients less than 40 years in Varun Arjun Medical College, Banthra, Shahjahanpur over 2 years. Material and methods: The present study was performed in 100 patients (50 males and 50 females) of dilated cardiomyopathy over 2 years. Diagnosis of dilated cardiomyopathy was done by echocardiography. After selection of patients, detail history and complete clinical examination was carried out. ECG and Echocardiography was done among all these patients using standard techniques. Results: The axis was normal in majority (85%). Left axis deviation was seen in 9% and right axis deviation in 6%.  The most common abnormality was ventricular ectopics seen in 43% of patients. Sinus tachycardia and left bundle branch blocks were seen in 40% of subjects. Non specific ST-T changes were seen in 27% whereas atrial fibrillation was present in 12%. LVH was seen in 20% and left atrial enlargement in 14% of subjects.
