摘　　要：很多房性心动过速、心房扑动和心肌梗死后室性心动过速是折返造成的。这些折返环通过导管激动顺序标测很难确定。拖带是电生理的一个重要概念,拖带技术在导管标测时,依据不同部位起搏时,标测电位图的比较,观察起搏位点与折返环的关系,揭示折返心律失常的特征。拖带技术可区分位于折返环上及折返环外的起搏点、确定折返环异常传导区域,指导治疗折返性心律失常。拖带标测已被用于心房扑动、折返性房性心动过速与瘢痕有关的室性心动过速的治疗。现将介绍拖带标测对诊断折返引起心律失常的的应用价值。另外,将揭示显性拖带与隐匿性拖带的差异,最后,将介绍诊断和治疗心房扑动、室性心动过速的策略。Many atrial tachycardias, atrial flutter, and postmyocardial infarction ventricular tachycardias are due to reentry through large ＂maeroreentrant＂ circuits. These circuits can be difficult to define by catheter mapping of the activation sequence. Entrainment map- ping is an important concept in electrophysiology. Entrainment techniques allow the relationship of a mapping site to the reentrant circuit to be assessed on a site-by-site basis during catheter mapping. Regions of abnormal conduction that are in the reentrant circuit can be distin- guished from bystander sites outside the circuit. A mapping site classification to guide catheter ablation is reviewed in this article.
