27. CONCLUSION:-
Antiarrhythmic drugs exert their effect by modulating conduction velocity or refractive
period duration or both.
Conduction velocity depends on passive electrical properties of cardiac tissue or
characteristics of Na+ and Ca²+ channel.
In contrast there are marked difference among species in the K+ currents that largely
determine repolarization, so that AP duration & duration of refractory period differ widely
various species.
It is clear that species difference do exist with respect to factors that determine
arrhythmogenesis & it ia also clear that no animal models will mimic the human suffering
from or threatened by arrhythmia.
Electrophysiological studies should be encouraged in animals with naturally occurring
cardiovascular disease.
