ABSTRACT
Antiarrhythmic effect of isoliensinine (IL) was studied on experimental arrhythmic mo-dels induced by coronary artery ligation and 4 different arrhythmogenic drugs in comparison with quinidine(Qu). Results of the study showed that the antiarrhythmic potency of IL was stronger than that of Qu atthe same dosage. The effects of IL on fast and slow response action potentials of myocardium were ob-served in guinea pig papillary muscles by standard microelectrode technique, which showed that IL couldreduce APA and Vmax and shorten the APD50. The results suggested that the antiarrhythmic mechanismof IL is related to its non-specific inhibition of the currents of Na+ and Ca2+.
