本文对５３例各种不同类型的心律失常进行了食管电生理检查，共检出房室结双径路２０例。９例有室上性心动过速（ＰＳＶＴ）史，其中４例诱发出ＰＳＶＴ（２０％），并通过超速抑制终止其发作；９例有窦缓史，其中２例经食管电生理检查诊断为病窦。在此类患者中，发现房室结双径路，在国内尚未见报道。经统计学处理，ＰＳＶＴ与窦缓两者的电生理参数除后者窦房结恢复时间显著延长（Ｐ＜０．０１）外，余均无显著差异。作者认为房室结双经路的存在与窦房结功能是否正常无关，并提出房室结双径路与病窦共存的电生理现象。在２０例房室结双径路中还发现多经路５例（２５％），房室传导间隙６例（３０％）。
In this paper, 53 cases of different types of arrhythmia were esophageal electrophysiological examination were detected in 20 cases of atrioventricular node dual pathway. Nine patients had a history of supraventricular tachycardia (PSVT). Four of them had PSVT (20%) evoked, and their seizures stopped by speeding. Nine patients had history of sinus delay. Two of them were diagnosed as esophageal electrophysiology Sick sinus. In such patients, found that atrioventricular node dual pathways, has not been reported in China. Statistically, the electrophysiological parameters of PSVT and sinus slowing were not significantly different except for the recovery time of the sinoatrial node (P <0.01). The author believes that the existence of atrioventricular node dual pathway has nothing to do with whether the function of the sinus node is normal or not, and presents the electrophysiological phenomenon that coexistence of atrioventricular node dual pathways and sick sinus. In 20 cases of dual atrioventricular node pathways also found in more than 5 cases (25%), atrioventricular conduction gap in 6 cases (30%).
