Ventricular Tachyarrhythmias Clinical Trial
Official title:
Ablation of Ventricular Fibrillation by Accurate Targeting of Arrhythmogenic Regions (AVATAR)
This study will test the hypothesis that many human heart rhythm disorders are caused by small localized sources, where brief ablation may successfully eliminate the heart rhythm disorder.
The investigators will enroll patients with documented rapid heart rates from the bottom
chambers of the heart (ventricular tachyarrhythmias).
During electrophysiological study, the investigators will map the localized sources of these
heart rhythm disorders.
1. The 'active' group will prospectively receive brief ablation at localized sources (Focal
Impulse and Rotor Modulation, FIRM).
2. The control group will be a historical cohort who have received traditional ablation for
this disorder.
All patients will be followed for up to 1 year to ensure that they have no recurrent
arrhythmias.
