心室流出道（ ventricular outflow tract ，VOT）起源室性早搏（ premature ventricular contraction ，PVC）因临床常见，具有典型的心电图（ ECG）特征，诊断并不困难，射频消融术是该病非药物治疗的主要手段。文中报道1例初步诊断右心室流出道起源（ RVOT）的PVC的患者，于左心室流出道（ LVOT）获得成功消融的诊治经过。文献复习了PVC定位的方法、VOT局部独特的解剖特点对定位的影响，以及三维标测新技术对PVC消融手术的帮助。

Premature ventricular contraction ( PVC) originating from ventricular outflow tract ( VOT) is easy to be diagnosed because it is common in clinic and of marked feature of Electrocardiogram (ECG).Radiofrequency catheter ablation (RF ablation) has became the major technique to treat the PVC besides drug treatment .The article reports one case firstly diagnosed as PVC from right VOT was finally RF ablated successfully at left VOT .The review of literature emphasizes the way to locate the PVC from VOT , the in-fluence of particular local anatomic structure between the right and left VOT on locating the PVC and the advantage brought by new 3-D mapping system .
