The study was undertaken with the objective to diagnose different types of cardiac abnormalities in dogs. The ECG of selected dogs was performed by multi-parameter monitor and single channel ECG machine. The prevalence of cardiac abnormalities was 2.41 percent (40/1655) and amongst the suspected cases (40/98) it was 40.81 percent. The prominent clinical signs observed with highest frequency of 65.00 percent were persistent coughing/dyspnea followed by 47.50, 40.00, 27.50, 15.00, 7.50 and 5.00 percent lethargy/dullness/depression, anorexia/reduced appetite, exercise intolerance, abdominal distension, sudden fainting/syncope and limb edema respectively. The higher prevalence of sinus arrhythmia was 22.50 percent followed by atrial fibrillation 20.00 percent, sinus tachycardia 10.00 percent, left ventricular enlargements 10.00 percent. Prevalence of right atrial enlargement, left atrial enlargement, first degree AV block, second degree AV block and ventricular premature complexes had been observed in two dogs for each indicating 5.00 percent prevalence. Atrial premature complexes, myocardial hypoxia, ventricular hypertrophy, right bundle branch block and sinus bradycardia showed 2.50 percent prevalence rate in one dog each.
