Ablation of idiopathic ventricular fibrillation triggered by ventricular premature beat originating from myocardium of right ventricle: Case report

We report a case of a 55-year-old woman with idiopathic ventricular fibrillation (VF) who suffered from recurrent implantable cardioverter-defibrillator shocks triggered by short coupled ventricular premature beat (VPB). This VPB was mapped and ablated from the myocardium of right ventricle close to the lateral tricuspid annulus.
