摘　　要：心室流出道是特发性室速/室早常见的起源部位(约70%起源于右室流出道)。针对有症状的室性早搏高负荷、室性心动过速性心肌病及不能耐受药物治疗的患者,可采用导管消融治疗。该治疗手段成功率高、复发率低且并发症少,是目前重要的治疗方法之一。本文旨在学习右室流出道室性心律失常的临床电生理特点,以指导临床诊治。Ventricular outflow tract is a common origin of idiopathic ventricular tachycardia or premature ventricular contraction(PVC),about 70%of which originates from the right ventricular outflow tract.The catheter ablation can be applied on symptomatic PVC patients with high load,patients with ventricular tachycardia cardiomyopathy and those being intolerant of medication therapy.At present,the ablation method becomes one of the important therapies with high success rate,low recurrence rate and fewer complications.This paper summarizes the clinical electrophysiological features of ventricular arrhythmias originating from the right ventricular outflow tract so as to clinically guide the diagnosis and treatment.
