In patients with no evidence for structural heart disease, idiopathic ventricular fibrillation and polymorphic ventricular tachycardia (PVT) are frequently triggered by ventricular premature beats (VPBs) arising from the Purkinje system or the right ventricular outflow tract that can be successfully eliminated by radiofrequency (RF) catheter ablation.1, 2 Such triggers of malignant arrhythmias have also been demonstrated and successfully eliminated in patients with Brugada, long QT, and early repolarization syndromes.3, 4, 5 We report a case involving a patient with Brugada syndrome in whom malignant PVT was eliminated by RF ablation of VPBs as a trigger originating from the left fascicular conduction system.
