A study was conducted to determine the reference ranges of electrocardiographic parameters in New Zealand white pet rabbits in Andhra Pradesh of India. Thirty two rabbits aged between 8 to 24 months belongs to the both the sexes were used for this study. Mean rectal temperature, heart rate, respiratory rate and arterial blood pressure 102.38 ± 0.15°F, 209.166 ± 3.21beats per minute, 48.30 ± 1.90 21beats per minute and 118 ± 8.65/ 77 ± 7.2 mm Hg respectively. Recorded P wave, QRS complex and T wave amplitudes range from 0.05 to 0.10 mV, 0.15 to 0.30 mV and 0.10 to 0.20 mV respectively in all the rabbits. Duration of P wave, QRS complex and T wave was between 0.02 to 0.04, 0.02 to 0.06 and 0.07 to 0.08 seconds respectively in all the rabbits. P-R interval was between 0.04 to 0.08 seconds and Q-T interval was between 0.08 to 0.12 seconds in all the rabbits. Mean cardiac electrical axis recorded in rabbits was bewteen - 30° to + 130°. There is no gender difference effect on electrocardiographic parameters in rabbits.
