dc.description.abstractEffect of propranolol (1 and 3 mg/kg body wt), a sympathetic blocking agent, on ECG patterns was studied in Varanus and Acridotheres. ECG was recorded before and after 5 min (immediate), 15 min and in some cases 25 min of drug infusion. All animals responded to propranolol with bradycardia. The effectiveness is dose dependent and it is also associated with the high heart rate both in Acridotheres and in Varanus. The P-R or P-S interval increased in all cases of Varanus after infusion. In Acridotheres height and duration of P-wave were increased slightly with the lower dose and decreased with the higher dose. The Q-S shortened with the lower dose and widened late with the higher dose in Varanus whereas in Acridotheres it is widened with lower and higher doses of propranolol. The Q-T interval has been increased in both groups of animals. An increased amplitude of T-wave height was observed in Varanus after 5 and 15 min of drug infusion. But it was noted with decrease in amplitude under high dose after 15 min of drug infusion. In Acridotheres it was on increase with lower dose and decrease with higher dose. The delta-wave disappeared after the administration of propranolol in Acridotheres.(ABSTRACT TRUNCATED AT 250 WORDS)en_US
