If the ventricular tachycardia recurs, supplemental amiodarone infusions of 150 mg over 10 minutes can be given.

If the patient is stable, intravenous procainamide, 20 mg/min intravenously (up to 1000 mg), followed by an infusion of 20-80 mcg/kg/min could also be tried.

Empiric magnesium replacement (1 g intravenously) may help.

Ventricular tachycardia can also be terminated by ventricular overdrive pacing.
