Electrocardiographic technique was analysed in normal dairy cows in order to evaluate the electrical activity of heart and hence to detect abnormalities like cardiac arrhythmia and electrolyte disturbances which is very common in cattle. The base apex system seems to be the best and standard lead which gives clear electrocardiographic changes. The present study was conducted on normal dairy cows with no cardiac arrhythmias or abnormal heart sounds presented to the Large Animal Unit of TVCC, Rajiv Gandhi Institute of Veterinary Education and Research, Puducherry. The positive electrode of limb lead 1 was attached to the fifth intercostal space and negative electrode on the jugular furrow and the neutral on the withers. The electrocardiogram was obtained on a single channel ECG machine with paper speed of 25 mm/sec and calibration of 10mm equal to 1mV. The P wave was positive in all cases and the QRS complex was negative. Amplitude of ECG waves and duration of P, QRS, and T and intervals of P-R and Q-T were also recorded.
