文摘

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.

<Learning objective: Triggering ventricular premature beat (VPB) in idiopathic ventricular fibrillation was reported to originate from the myocardium of right ventricular outflow tract or from Purkinje system. In this case, the origin of triggering VPB is the myocardium of right ventricle close to the lateral tricuspid annulus.>
