Combining noninvasive electrocardiographic imaging mapping method with fluoroscopic integration module enables the idiopathic ventricular fibrillation ablation triggered by rare premature ventricular contraction

Idiopathic ventricular fibrillation (IVF) is a primary cause of sudden cardiac death in young patients, especially in those without any structural or electrical heart abnormalities.1 Premature ventricular contractions (PVCs) inducing IVF have been reported to be particularly related to short-coupled PVCs (coupling interval ≤350 milliseconds), which mostly originate from Purkinje systems.2–4 Invasive mapping of originating PVCs can be difficult due to VF induction by catheter manipulation or pace-map and anatomic difficulties.
