Amiodarone Flashcards

Q
What is the mechanism of Amiodarone?
A
●It is an antidysrhythmic with broad spectrum activity.
●Has class 3 activity, prolongs the action potential duration, reduces automaticity and prolongs the refractory period of atrial, nodal, and ventricular tissues.
●The electrophysiological effects result in a reduction in abnormal electrical activity, conduction, and HR, and stabilises the SA and AV nodes.
