摘　　要：为探讨食管心房调搏揭示室上性心动过速发生机制的价值和局限性 ,回顾性分析成功射频导管消融的138例隐匿性单房室旁道参与的顺向型房室折返性心动过速和100例单一类型房室结折返性心动过速的食管心房调搏结果。结果显示 :前138例中 ,3例前间隔旁道引起者食管心房调搏均诊断为房室结折返性心动过速 ,余为左右侧其它部位的旁道 ,诊断正确。后100例中 ,5例为慢_慢型 ,2例为快_慢型 ,食管心房调搏均诊断为房室折返性心动过速 ;余为慢_快型 ,与食管心房调搏诊断一致。提示食管心房调搏是目前鉴别两者的最佳无创性方法 ,但前间隔旁道引起者易误诊为房室结折返性心动过速 。To investigate role of transesophageal atrial pacing(TEAP) in diagnosis of supraventricular tachycardia,results of TEAP were analysed in 138 patients with orthodormic atrioventricular reentrant tachycardia(O _ AVRT) mediated by concealed single atrioventricular accessory pathways(AP) and 100 patients with single atrioventricular nodal reentrant tachycardia(AVNRT).Results showed that among 138 cases of 0 _ AVRT and 3 cases of 0 _ AVRT mediated by anteroseptal AP were correctly diagnosed as AVNRT during TEAP,and correct diagnosis were made for other cases of AVRT.Among 100 patients with AVNRT,5 cases had slow _ slow form,2 fast _ fast AVNRT,and 7 cases were AVRT during TEAP.Diagnosis of 93 cases of slow _ fast AVNRT were identical with TEAP.Results suggest:TEAP is best noninvasive method in diagnosis of CAP mediated O _ AVRT and single AVNRT,but anteroseptal AP mediated AVRT was often misdiagnosed as AVNRT,and slow _ slow and fast _ slow AVNRT often as AVRT.
