食管心房调搏诊断室上性心动过速的局限性探讨

A study of limitation of trans-esopbageal atrial pacing in diagnosing supraventricular tachycardia

对１２０例室上性心动过速（ＳＶＴ）患者的食管心房调搏（ＴＥＡＰ）与心内电生理检查的结果进行比较，发现两者不符有２０例，进一步分析表明属ＴＥＡＰ漏诊或误诊，其原因除与ＳＶＴ自身的电生理特性有关外，更主要的是与ＴＥＡＰ方法学上存在一定缺陷有关。

Compared the results of trans-esophageal atrial pacing(TEAP)with those of intracardiac electrophysiology,discord between them was found in 20 of 120 patients with supraventricular tachycardia(SVT).Analysed the results of TEAP and intracardiac electrophysiology,and compared methodology between TEAP and intracardiac electrophysiology,the causes of discord was found mainly due to missing-diagnosis or misdiagnosis of TEM in diagnosing SVT.The reason did not only correlated with the charactristics of electrophysiology of SVT,but more correlated with the disadvantage of methodology of TEM.
