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、筛选短不应期旁道、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。

Abstract：To evaluate the diagnostic value of transesophageal atrial pacing (TEAP)for superventricular tachycardia (SVT) and the reliability of parameters measured by TEAP.Fifty-eight patients with patoxysmal superventricular tachycardias (PSVT) were studied by transesophageal atrial pacing as well as intracardial electrophysiological study.Among the forty-nine cases whose SVTs were evoked by TEAP. There was no significant difference between the diagnosis using TEAP with those using IEPS. There were no differences between the following parameters by TEAP and those by IEPS:the 2:1 atrioventricular block point in patiens with atrioventricular nodal reentrant tachycardia of slow-fast type (AVNRT S-F) or the atriventricular reciprocating tachycardia (AVRT),the effective refractory period of overt accessory pathway (Ap-ERP),and the induced area of SVT. The diagnosis of SVT with totally fits well with that with IEPS.

TEAP检查是一种用来检测窦房结、房室结功能，诊断和终止SVT等的无创性检查方法。由于其简便、安全、费用低和易被患者接受，在临床上得到了广泛应用，但对TEAP的电生理参数是否和IEPS的结果一致研究尚少。我们对比研究了TEAP和IEPS对SVT的检查结果，对TEAP电生理参数的可靠性进行了相关评价。
