Introduction
Fatal ventricular arrhythmias have an increased incidence in the case of structural heart diseases such as ischemic cardiomyopathy. It is known that ventricular premature contractions (PVCs) originating from Purkinje fibers can induce polymorphic ventricular tachycardia (PMVT) and, subsequently, ventricular fibrillation (VF) in patients with ischemic cardiomyopathy., Ventricular arrhythmias associated with Purkinje usually do not respond to conventional antiarrhythmic drugs. Catheter ablation is a favorable and life-saving treatment strategy for VF triggered by Purkinje fibers.
