摘要:: 目的:探讨经食管心房调搏对不同类型房室结折返性心动过速诊断的准确性。方法:收集近5个月经心内电生理检查（标准诊断）确诊为房室结折返性心动过速（AVNRT）196例，与其食管调搏的诊断进行比较。结果:两种电生理检查诊断慢-快型AVNRT符合率100%，但食管电生理检查对快-慢型AVNRT及慢-慢型AVNRT与起源于心房下部靠间隔的房速不易鉴别。结论:经食管心脏电生理检查对慢-快型AVNRT具确诊价值。对快-慢型或慢-慢型AVNRT容易误诊为房速。

Abstract:: AIM:To study the diagnostic accuracy of esophageal pacing in different types of atrioventricular nodal reentrant tachycardia (AVNRT). METHODS: One hundred and ninetysix patients were diagnosed with AVNRT by intracardiac electrophysiology and the results were compared with the findings of esophageal pacing. RESULTS: The coincidence rate of the two methods in diagnosing the slowfast AVNRT was 100%. However, esophageal pacing was not very effective in discriminating the fastslow AVNRT and slowslow AVNRT from atrial tachycardia. CONCLUSION: Esophageal pacing is of high diagnostic value only in the slowfast form of AVNRT. For accurate diagnosis of fastslow AVNRT and slowslow AVNRT, intracardiac electrophysiology should be performed.
