摘　　要：目的探讨食管心电图对室上性心动过速时隐匿性预激旁道的诊断和定位标准。方法观察124例经射频导管消融证实的隐匿性预激旁道合并室上性心动过速时食管心电图改变与旁道诊断定位的关系 ,并与56例经射频导管消融证实的房室结双径路结果作对照。结果隐匿性旁道的食管心电图示有P′ESO 波 ,R_P′ESO 间期≥80ms ,无文氏传导现象 ,但常出现束支传导阻滞 ,且符合Coumel_Slama定律。如以P′R 与P′S 波位置关系为隐匿性旁道定位标准 ,定位准确率均达86 %以上。Objective To study relative relationship of diagnosis criteria and locating of atriventricular accessory pathways in concealed preexcitation(CAP) with supraventricular tachycardia(SVT)by esophagocardioelectrogram.Methods Results of 124 cases of CAP and 56 cases of double atrioventricular nodule with radiofrequency ablation(RFCA) for good standard were compared to study relative relationship of diagnosis criteria and locating accessory pathways by esophagocardioelectrogram in CAP with SVT.Results Diagnosis criteria of CAP was estabished by esophagocardioelectrogram,it was included 100% presence rate of P′ESO wave,R _ P′ESO interval≥80 ms and revealing no Wenckebach phenomenon but hemiblock being quite common in conforminty with Coumel _ Slama rule.Locating crteria of CAP was confomed by relationship of P′R and P′S wave in esophagocardioelectrogram,Its locating crteria accurate rate over 86%.Conclusion Esophgaocardioelectrogram was of help to diagnosis preexcitation criteria and roughly locating.
