BACKGROUND The burden of cardiomyopathy in the Indian population is huge. The prevalence of heart failure is about 1 to 1.5% of the adult population. The incidence of DCM is reported to be 5 to 8 cases per 1,00,000 population per year. It is three times more common in men as compared to women. Dilated cardiomyopathy is the most common variety of cardiomyopathy. The annual mortality rate for a typical patient of DCM with heart failure is about 11 to 13 percent. Dilated cardiomyopathy is the most common indication for cardiac transplantation in the west. MATERIALS AND METHODS This study was undertaken to evaluate the electrocardiographic and echocardiographic profile of patients with dilated cardiomyopathy in a tertiary care centre. Detailed clinical evaluation followed by ECG and 2D-echo were done. 30 subjects were included. The ECG and echocardiographic parameters of the patients were tabulated and analyzed. RESULTS The most common abnormality was ventricular ectopics which was seen in 46.6% of patients. Sinus tachycardia and left bundle branch blocks were seen in 40% of subjects. Right bundle branch block was observed in 13.3%. The mean LV ejection fraction was 30.87%. In our study, 73.3% had mitral regurgitation, 10% had tricuspid regurgitation, and pericardial effusion was seen in 6% of patients. Biventricular failure was seen in 80% of patients; isolated LV failure was seen in 16.6% and RV failure in 3.3%. CONCLUSION ECG AND 2D-Echocardiography are cornerstones for the diagnosis and management of patients with dilated cardiomyopathy.
