特发性室性心动过速(idiopathic ventriculartachycardia,IVT)是指一组没有明显心脏结构和功能异常的室性心动过速(VT),是临床上较少见的心律失常,其发生率约占所有室速的10％左右。根据其起源部位有特发性左心室室性心动过速(ILVT)和右心室流出道室性心动过速(RVOT-VT),以起源于左心室间隔部的ILVT最为常见。近年来,随着对IVT的发生机制、电生理机制和治疗方法等方面的深入发展,尤其是心内标测技术的发展和导管射频消融技术在根治这类室速中的应用,不仅对ILVT和RVOT-VT有了深入 Idiopathic ventriculartachycardia (idiopathic ventriculartachycardia, IVT) refers to a group of no obvious cardiac structure and dysfunction of ventricular tachycardia (VT), is clinically rare arrhythmia, the incidence of about About 10% of all VT. According to its origin of idiopathic left ventricular ventricular tachycardia (ILVT) and right ventricular outflow ventricular tachycardia (RVOT-VT), to originate in the left ventricular septal ILVT most common. In recent years, with the in-depth development of IVT mechanism, electrophysiological mechanism and treatment methods, especially the development of intracardiac mapping technology and catheter radiofrequency ablation in the cure of such VT, not only for ILVT And RVOT-VT has been in-depth
