Key result
Combination antiarrhythmic therapies, particularly class IA with IB or II agents, show higher efficacy and lower toxicity than individual agents for ventricular tachyarrhythmias.
Why the study?
Does combination antiarrhythmic drug therapy improve efficacy and reduce toxicity compared to single agents in patients with ventricular tachyarrhythmias?
Population

May support combinations in refractory ventricular tachyarrhythmias; leaves open need for randomized confirmation before practice change.
Does combination antiarrhythmic drug therapy improve efficacy and reduce toxicity compared to single agents in patients with ventricular tachyarrhythmias?
Combination antiarrhythmic therapy, particularly class IA with IB or class IA with II agents, may offer higher efficacy and lower toxicity for ventricular tachyarrhythmias compared to monotherapy.
Greenspan et al. (1986) conducted a review in Ventricular tachyarrhythmias. Combination antiarrhythmic drug therapy vs. Individual agents alone was evaluated. Combination antiarrhythmic therapies, particularly class IA with IB or II agents, show higher efficacy and lower toxicity than individual agents for ventricular tachyarrhythmias.
