Q
Actions (2)
A
- Noncompetitive alpha/beta adrenergic blocking properties
- Prolongs duration of action potential and effective refractory period which slows conduction

A
Class III Antidysrhythmic
3
Q
Indications (4)
A
- VF or VT cardiac arrest
- Control of hemodynamically stable VT, polymorphic VT, and wide-complex tachycardia of uncertain origin
- Refractory PSVTs, atrial tach, and pharmacological cardio version of AF
- Control rapid ventricular rate due to accessory pathway conduction in preexcited atrial arrhythmias
