Abstract
The present study was conducted to study clinical profile, electrocardiographic profile, to compare the efficacy of ECGs, radiography and cardiac Troponin I and undertake rationale treatment. The overall prevalence rate of cardiomyopathy in dogs was 6.57% (23/350). Pomeranian and German Shepherd dogs predominated the scene with higher frequency of cardiomyopathy in male dogs. Age group of more than 5 year old had high frequency of cardiomyopathy. Anorexia/reduced appetite, weakness/depression/dullness, easy exertion, refractory appetite, ascites, posterior weakness, coughing, dyspnoea, Jugular distension/ pulsation, mucus membrane pale/muddy/ cyanotic, weight loss, weak femoral pulse/ pulse deficit and syncope were predominant clinical signs of cardiomyopathic dogs. Radiographic silhouette of the heart in most cases was within limit and vertebral heart score (VHS) was more than or equal 8.7 to less than or equal 10.7. On the basis of electrocardiographic features 11 types of cardiomyopathy were diagnosed as sinus tachycardia (8.69%), sinus arrhythmia (4.34%), right atrial enlargement (4.34%), left atrial enlargement (21.73%), atrial tachycardia (8.69%), atrial fibrillation (17.39%), atrial premature complex (8.69%), left ventricular enlargement (34.78%), ventricular premature complex (13.04%), ventricular tachycardia (8.69%) and sinus arrest (13.04%).
In most of cases (95.65%) cardiac Troponin I was found positive (>0.1ng/ml). Cardiac Troponin I is highly sensitive to diagnose the cardiomyopathy.
