In several cases with idiopathic ventricular fibrillation (VF), VF was initiated by premature ventricular contractions (PVCs) from the Purkinje system. However, the precise characteristics of the Purkinje activity in patients with idiopathic VF remain unclear. We performed an electrophysiological study in a patient with idiopathic VF and examined the correlation between the Purkinje potential and the incidence of PVCs/polymorphic ventricular tachycardia (PMVT). In this case of idiopathic VF, the Purkinje activity caused multiform PVCs and PMVT. The The Purkinje activity and slow conduction of Purkinje fibers are associated with the occurrence of multiform PVCs and PMVT.
在几例特发性心室颤动（VF）患者中，VF由浦肯野系统的室性早搏（PVC）引发。然而，特发性VF患者中浦肯野活动的精确特征仍不清楚。我们对一名特发性VF患者进行了电生理研究，并检查了浦肯野电位与PVC/多形性室性心动过速（PMVT）发生率之间的相关性。在这例特发性VF中，浦肯野活动导致了多形性PVC和PMVT。浦肯野活动及浦肯野纤维的缓慢传导与多形性PVC和PMVT的发生有关。
