摘　　要：通过58例食管心房调搏（TEAP）与心腔内电生理检查（IEPS）的对比研究，评价TEAP对室上性心动过速（SVT）的诊断价值及TEAP各电生理参数的可靠性。TEAP诱发的49例SVT中，TEAP与IEPS的诊断完全符合。房室传导系统的2：1阻滞点、旁路前传有效不应期（AP－ERP）、SVT诱发带等在TEAP和IEPS两组间无显著性差异（P＞0．05）。认为TEAP在了解房室传导系统的前传功能、筛选短不应湖旁道、测定SVT的诱发带、鉴别AVNRT与AVRT以及分辨左、右侧旁道引起的AVRT等方面有很高的实用价值。To evaluate the diagnostic value of transesophageal atrial pacing (TEAP) forsuperventricular tachycardia (SVT) and the reliability of parameters measured by TEAP. Fiftyeight patients with patoxysmal superventricular tachycardias (PSVT ) were studied bytransesophageal atrial pacing as well as intracardial electrophysiological study. Among the rortynlne cases whose SVTs were evoked by TEAP. There was no significant difference between thediagnosis using TEAP with those using IEPS. There were no differences between the followingparameters by TEAP and those by IEPS: the 2: 1 atrioventricular block point in patiens withatrioventricular nodal reeutrant tachycardia of slow-fast type (AVNRT S-F) or the atriventricularreciprocating tachycardia (AVRT),the effective refractory period of overt accessory pathway (APERP),and the induced area of SVT. The diagnosis of SVT with totally fits well with that withIEPS.
