Intervention
Catheter ablation targeting ventricular premature contraction (VPC) triggers and substrate modification
Catheter ablation can effectively suppress ventricular fibrillation through the elimination of triggering ventricular premature contractions and modification of the arrhythmogenic substrate.
Limitations
- Further studies are needed to evaluate the precise mechanisms of this arrhythmia.
