The effect of adrenaline and studied compounds on mortality of rats in prophylactic adrenaline-induced arrhythmia. Rats were anesthetized with intraperitoneal (i.p.) injection of thiopental (75 mg/kg). The tested compounds were administered (i.p.) 45 min before the experiment. The observation was carried out for 15 min after the intravenous injection of adrenaline (20 μg/kg). n = 5−6 animals per group.
