The study was undertaken in twenty three (23) dogs with cardiac insufficiency. The dogs showing signs of chronic cough, exercise intolerance, abdominal distension and syncope were selected and on the basis of electrocardiography (ECG) and echocardiography were diagnosed to be suffering from cardiac diseases (dilated cardiomyopathy-19 and hypertrophic cardiomyopathy-4). ECG findings in dilated cardiomyopathy (DCM) were supraventricular tachycardia, P mitrale, P pulmonale and increasd R amplitude. M mode changes in DCM were significant increase in left ventricle (LV) dimensions, thinning of interventricular septum (IVS) and LV posterior wall, significantly reduced fractional shortening (FS%) and ejection fraction (EF%). M mode changes in hypertrophic cardiomyopathy (HCM) were decreased lumen of ventricles and increased thickening of walls and IVS. Dilated cardiomyopathy is the most common cardiomyopathy in dogs and echocardiography is the most efficient procedure for differentiation between dilated and hypertrophic cardiomyopathy.
