摘要
目的分析先天陛心脏病外科手术后心房内折返性心动过速（intra-atrial reentrant tachycar-dia，IART）心电图与消融靶点的关系。方法选择2004年1月至2005年12月在我院因先天性心脏病外科手术后LART行射频消融的24例患者，回顾性分析患者的心电图（F波或P’波）与消融靶点的关系。结果24例患者共诱发出28种IART。17种（17／28，60．7％）IART心电图表现为典型锯齿形F波，其中15种（15／17，88．2％）成功消融靶点在下腔静脉和三尖瓣环（IVC-TA）峡部；另外11种（11／28，39．3％）IART临床心电图表现与典型心房扑动不同，表现为P’波，其中7种（7／11，63．6％）IART成功消融靶点在右心房游离壁瘢痕-下腔静脉，其他分别在IVC-TA、界嵴前方、间隔补片和上腔静脉之间、房间隔补片处消融成功。结论不同部位的IART具有一定的心电图特点，根据这些心电图特点，有助于消融靶点的判定。
Objective The purpose of this study is to observe the relationship between electrocardiogram and ablation targets of intra-atrial reentrant tachycardia（IART） after congenital heart disease surgery. Methods Twenty-four patients of IART after congenital heart disease surgery received ablation in our hospital from January 2004 to December 2005. IART were ablated by guidance of three-dimensions mapping system （Carto or EnSite 3000）. The relationship between tachycardia electrocardiogram（ F waves or P＇ waves）and the ablation targets were investigated, respectively. Results Twenty-eight kinds of IART were induced in 24 patients. Seventeen（ 17/28,60. 7% ）kinds of IART electrocardiogram showed typical F waves, of which the success- ful ablation targets located between the inferior vena cava-tricuspid annulus （IVC-TA）isthmus inl5 （15/17, 88.2% ） kinds of IART. Another 11 （ 11/28,39.3 % ） kinds of IART electrocardiogram showed P＇ wave, of which the successful ablation targets located on the right free wall scar-IVC isthmusin 7 （7/11,63.6%）kinds of IART. The other IART successful ablation targets located on IVC-TA, crista terminalis, septal patch-superior vena cava, atrial septal patch ,respectively. Conclusion The electrocardiogram could be helpful to the judgment of the ablation targets with IART.
