Q

Amiodarone

Type

A

Amiodarone has effects within the first four classes of the Vaughan-Williams classification. However it is primarily classified as a Class III antidysrhythmic agent that prolongs the action potential duration and hence the refractory period of atrial, nodal and ventricular tissue. It has characteristics of all Vaughan-Williams classes of antidysrhythmics.
