    Transesophageal atrial pacing distinguishes Mahaim fibers

      摘要
    • 摘要: 目的:通过食道心房调搏技术鉴别Mahaim纤维。方法：回顾性分析53例旁道具有前传功能患者的食道电生理检查。其中Mahaim纤维组7例,Kent氏束组46例,对比两组的经食道心房起搏后S-R间期、旁道递减功能（ΔS-R）、旁道不应期（AP-ERP）、及心动过速发作特点。结果：在经食道心房调搏检查中，S1S1起搏时Mahaim纤维组S-R间期较Kent氏束组长［(71±20)ms vs. (28±14)ms,P<0.05］；Mahaim纤维组可见ΔS-R［(103±28)ms vs.(12±11)ms，P<0.01)；两者的AP-ERP无显著差异。Mahaim纤维组7例均诱发出宽QRS波心动过速，Kent氏束组3例为宽QRS波心动过速。结论：应用经食道心房调搏可鉴别Mahaim纤维。

       

      Abstract: AIM:To distinguish Mahaim fibers by transesophageal atrial pacing. METHODS: Fifty three patients were divided into Mahaim group (n=7) and Kent group (n=46). The interval of stimulus to QRS wave (S-R), accessory pathway progressive decrease conduction (ΔS-R), accessory pathway effective refractory period (ERP), and characteristics of tachycardia were examined by transesophageal atrial pacing. RESULTS: S-R in Mahaim group was longer than that in Kent group (71±20) msec vs. (28±14) msec (P<0.05), ΔS-R in Mahaim group and Kent group was, respectively, (103±28) msec and (12±11) msec (P<0.01). No statistical difference was observed in ERP between groups. CONCLUSION: Transesophageal atrial pacing could be used to distinguish Mahaim fibers.
