摘　　要：心外膜标测为我们更好地理解室速折返环的三维立体结构提供了基本信息。一旦选择了心外膜入路,多极标测、等时延迟激动标测等标测技术及改变波阵面等标测技巧,将有助于在尽量减少消融次数的前提下对关键区域进行有效消融。然而,要成功完成心外膜标测和消融,还需要对解剖结构有清晰的了解,从而最大程度提高成功率、减少并发症。Epicardial mapping provides essential information to better understand the threedimensionality of ventricular tachycardia circuits. Once epicardial access is obtained,mapping techniques such as multipolar mapping,isochronal late activation mapping and changing wavefronts can help determine essential regions for ablation,while limiting the amount of ablation required. However,successful epicardial mapping and ablation requires clear anatomic understanding to maximize success and minimize complications.
