ELECTROCARDIOGRAPHIC STUDIES IN HALLIKAR BULLOCK IN PUDUCHERRY REGION, INDIA

Fifteen Hallikar bullocks of eight to ten years old were presented to the Teaching Veterinary Clinical Complex of Rajiv Gandhi Institute of Veterinary Education and Research, Puducherry which were subjected to electrocardiographic examination. The electrocardiography was taken using bipolar base apex mode using limb lead II. Parameters recorded in electrocardiography were P wave amplitude and duration, QR and RS amplitude and QRS duration, T wave amplitude and duration, P-R duration and Q-T interval. The R wave is negative in bovine ECG. Electrocardiography revealed average increased in QR and RS amplitude and P-R duration indicative of ventricular hypertrophy.
