Electrophysiological mechanism and treatment of idiopathic ventricular tachycardia in children / 国际儿科学杂志

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.
