摘　　要：目的探讨食管心电图对隐匿性房室旁路的诊断价值。方法回顾性分析120例经心内电生理检查确诊为隐匿性房室旁路并获射频消融成功患者的食管电生理指标，总结心动过速发作时食管心电图表现与旁路诊断及定位的关系。结果49例左侧隐匿性房室旁路食管导联P波（P-E）领先体表V_1导联P波（P-V1）；38例右侧隐匿性房室旁路P-V1先于P-E；18例间隔隐匿性旁路P-E与P-V1几乎同时出现。结论食管心电图有助于隐匿性旁路的诊断和初步定位。Objective To evaluat the role of esophagus electrocardiogram in diagnosing of concealed atrioventricular pathway. Methods We retrospectively analyzed the characteristic manifestation transesophaged atrical pacing of 120 patients of concealed accessory atrioventricular pathway, which were diagnosed by intracardiac electrophysiology and concluded the characteristic of esophagus electrocar- diogram with SVT. To study relative relationship of diagnosis criteria and locating accessory pathwys. Results P-E was prior to Pw in 49 patients with left accessory pathway while P-V was prior to P-E in 38 patients with right accessory pathway during tachycardia. P-E and P-w occurenced simultaneously in 18 patients with midseptal accessory pathway.Conclusion Esophagus electrocardiogram was of help to diag- nosis concealed atrioventricular pathway and locating.
