摘　　要：特发性室性心动过速是指不伴有明确器质性心脏病的室性心动过速。起源于多个部位,包括左右心室以及大动脉的瓣膜上方。射频消融领域发展迅速,目前已作为首选治疗方法治疗那些引起严重症状的患者。手术成功率很高,尤其是在起源于右室流出道和左室左后分支折返的病例中。失败的原因主要是因为不能有效诱发出室性心动过速,以及那些起源于不能安全实施消融的部位。Idiopathic ventricular arrhythmias occur in patients without structural heart disease. They can arise from a variety of specif- ic areas within both ventricles and in the supra-valvular regions of the great arteries. The field of catheter ablation of idiopathic ventricular tachycardia has developed rapidly and ablation is currently recommended in patients with monomorphic ventricular tachycardia causing severe symptoms or when antiarrhythmic drugs are not effective, not tolerated, or not desired. The success rate of ablation of idiopathic ventricular tachycardia is high, especially in those arising from the right ventricular outflow tract and the interfascicular reentrant arrhythmias yield. Fail- ures are usually due to inability to induce the arrhythmia reliably or arrhythmia locations that are beyond safe access with an ablation catheter such as in the epicardial locations close to the coronary arteries.
