Intervention Details:
  • Procedure: Catheter ablation
    Mapping of the epicardium and ablating areas of long fractionated potentials

Primary Outcome Measures :
  1. Eradication of Brugada syndrome pattern [ Time Frame: 24h post procedure ]
    Disappearance of type 1 Brugada pattern on post-procedure ECG

Secondary Outcome Measures :
  1. Freedom from ventricular arrhythmias [ Time Frame: 12 months post-procedure ]
    No documentation of sustained ventricular tachycardia or ventricular fibrillation
