Mapping during ventricular tachycardia (VT) aims to elucidate mechanism, describe myocardial propagation, and identify the origin and critical regions of VT that can be targeted for ablation, most commonly with radiofrequency ablation. Most VTs in structural heart disease are due to macro-reentry in and around scar. A combination of mapping techniques, including mapping to identify the arrhythmia substrate, activation sequence mapping, pace-mapping, and entrainment mapping, may be used to identify putative ablation targets. This review describes the principles of entrainment mapping as it pertains to catheter ablation of scar-related VT.
室性心动过速（VT）标测旨在阐明机制、描述心肌传导，并识别可作为消融靶点的VT起源和关键区域，最常用的是射频消融。结构性心脏病中的大多数VT是由瘢痕内及周围的大折返引起的。多种标测技术的组合，包括用于识别心律失常基质的标测、激动顺序标测、起搏标测和拖带标测，可用于识别假定的消融靶点。本综述描述了与瘢痕相关VT的导管消融相关的拖带标测原理。
