Does electrophysiological study with antiarrhythmic drug testing predict long-term outcomes in patients with idiopathic ventricular fibrillation?
In patients with idiopathic VF, electrophysiological testing with double extra stimuli has a high yield for inducing VF, and suppression of inducibility by antiarrhythmic drugs predicts favorable long-term outcomes.
Aizawa et al. (1996) conducted an observational in Idiopathic ventricular fibrillation (n=8). Electrophysiological study and antiarrhythmic drugs was evaluated on Inducibility of ventricular fibrillation. Electrophysiological study using double extra stimuli successfully induced ventricular fibrillation in 75% (6 of 8) of patients with idiopathic VF.
