摘　　要：特发性室性心动过速(IVT)患者的心脏结构、功能无明显异常,发作时对血流动力学影响较小,患者耐受性较好。目前射频消融术已经成为根治这类室速的一种安全、有效的方法,IVT的心电图具有特征性的改变,通过心电图的精确定位有助于减少标测时间、提高消融成功率。现对近年来心内膜、心外膜IVT的各种起源部位,以及心电图特征图形的研究进展进行阐述。Patients with idiopathic ventricular tachycardia（IVT） have normal cardiac structure and function.At the onset of IVT,there are small impact on hemodynamic and the patients have better tolerance.At present,radiofrequency ablation has become a safe and effective method,which can cure IVT.The electrocardiogram of IVT has characteristic changes,by which the precise positioning can be realized to reduce mapping time and improve the rate of successful ablation.Here is to make a review on the recent progress of the research of various endocardial and epicardial origins,and electrocardiographic features of IVT.
