摘要

Key Teaching Points•Idiopathic ventricular fibrillation (IVF) is defined by ventricular fibrillation (VF) occurring in young adults with no discernible structural or electrocardiographic abnormalities.•A subset of IVF is induced by Purkinje ectopic beats (PurkE), and their ablation prevents VF recurrence.•Ablation of the surrounding Purkinje system without elimination of culprit PurkE may be sufficient to prevent VF recurrence. •Idiopathic ventricular fibrillation (IVF) is defined by ventricular fibrillation (VF) occurring in young adults with no discernible structural or electrocardiographic abnormalities.•A subset of IVF is induced by Purkinje ectopic beats (PurkE), and their ablation prevents VF recurrence.•Ablation of the surrounding Purkinje system without elimination of culprit PurkE may be sufficient to prevent VF recurrence.
