摘　　要：特发性室性心动过速(idiopathic ventricular tachycardia,IVT)是一种不伴有结构性心脏病和明确诱发因素的室性心动过速,在儿童中发病率较低,且总体预后好,但发作时间长可导致心功能不全甚至危及生命。根据IVT的起源、对药物的反应和心电图形态特征,可将IVT分为不同类型,其电生理机制也不尽相同。目前,抗心律失常治疗的适应证及具体治疗方案尚缺乏明确的指南。该文通过回顾IVT相关文献,对儿童IVT的电生理机制及治疗进展进行综述。Idiopathic ventricular tachycardia(IVT),which is a clinical entity without any structural heart disease or definite inducing factors,has a low incidence and a good overall prognosis in children,but long-term episode can lead to hemodynamic collapse or even be life-threatening.According to the origin of IVT,the response to drugs and the morphological characteristics of electrocardiogram,it can be divided into different subtypes whose electrophysiological mechanisms are also different.Besides,these is no guideline for the indications and treatment of IVT.This paper summarizes the electrophysiological mechanisms and progress of treatment of idiopathic ventricular tachycardia in children by reviewing the relevant literatures.
