摘要 目的:探讨经食管心房调搏对隐匿性房室旁道的诊断和定位特征。方法:回顾分析360例经心内电生理检查确诊为隐匿性房室旁道患者,总结其经食管心房调搏的特征表现。结果:Ⅰ导联P'倒置定位诊断左侧旁道的灵敏度为69%,特异度为98%;V1导联P'波直立定位诊断左侧旁道的灵敏度为71%,特异度为88%,V1导联P'双向定位诊断左侧旁道的灵敏度为14%,其特异度为95%,RP'E<RP'V1诊断左侧旁道的灵敏度为82%,特异度为99%。Ⅰ导联P'直立诊断右侧旁道的灵敏度为75%,特异度为93%,V1导联P'倒置诊断右侧旁道的灵敏度为65%,特异度为99%,RP'E>RP'V1诊断右侧旁道的灵敏度为82%,特异度为100%。结论:分析Ⅰ、V1导联P'特点和测量对比RP'E及RP'V1对隐匿性旁道诊断和粗略左右旁道定位具有重要价值。 AIM: To investigate diagnosis and analysis of localization characteristics of transesophaged atrial pacing in concealed accessory atrioventricular pathway. METHODS: We retrospectively analyzed 360 cases of concealed accessory atfioventricular pathway, which were diagnosed by intracardiac electro- physiology and concluded their characteristic manifestation transesophaged atrical pacing. RESULTS: The sensitivity of inverted P' wave in lead I in the diagnosis of left-sided accessory pathways was 69% , and the specificity was 98% , The sensitivity of upright P '-wave in lead V1 in the diagnosis of left-sided accessory pathways was 71%, and the specificity was 88%. The sensitivity of bidirectional P' wave in V1 lead in the diagnosis of left-sided accessory pathways was 14%. Specificity was 95%, sensitivity of RP'E 〈 RP'w in the diagnosis of left-sided accessory pathways was 82% , and the specificity was 99%. The sensitivity of upright P' wave in lead I in the diagnosis of right-sided accessory pathways was 75%, and the specificity was 93% , The sensitivity of inverted P' wave in lead V1 in the diagnosis of fight-sided accessory pathways was 65%, and the specificity was 99%. The sensitivity of RP's 〉 RP'v1 in the diag- nosis of right-sided accessory pathway was 82% , and the specificity was 100%. CONCLUSION: Ana- lyses of the P' wave characteristics in lead I and V1 and measuring or contrasting RP'E and RP'v1 has a significant value of diagnosis and localization of concealed accessory atrioventricular pathway.
