<unk>  Repetitive Monomorphic VT: amiodarone, beta-blockade (if tolerated), procainamide (IIA, C)<unk>  Polymorphic VT: Cardioversion for hemodynamic compromise (I, B), B-blockade (I, B), amiodarone if no LQTS (I, C), urgent angiography if ischemia not excluded (I, C)
Correction of electrolyte abnormalities (specifically hypokalemia) may decrease progression to VF.
Beta blockers
Initial therapy
May benefit patients with coexisiting cardiac conditions (CAD, CHF)
Verapamil, diltiazem
Second line therapies
Do not use in patients with uncontrolled heart failure.
Antiarrhythmic medications are generally reserved for patients that have failed beta blocker or calcium channel blocking who are NOT candidates for ablation procedures.  Expert consultation is advised.
