摘　　要：目的总结在经导管射频消融根治房室结折返性心动过速(AVNRT)时,进行房室结慢径改良过程中出现的心电现象。方法连续入选32例经电生理检查证实为典型(慢快型)AVNRT患者,进行房室结慢径改良射频消融术,观察在消融过程中腔内电图。结果消融中出现缓慢交界区心律后有5例出现快速交接区心律,3例不同程度VA阻滞现象,1例快速交界区心律并伴有V波脱落现象,1例AV间期延长;另1例消融过程中直接从窦律变为快速交界区心律而转为VA阻滞。结论房室结慢径改良射频消融过程中腔内电图上出现了各种预示房室传导阻滞的反应时应予以注意。Objective To observe the electrophysiologic phenomena during radiofrequency catheter ablation( RFCA) of the slow path for atrioventricular nodal reentrant tachycardia( AVNRT). Methods Enrolled 32 cases of typical( slow-fast) AVNRT undertaken RFCA,and studied their intracardiac electrograms during ablation. Results 11 cases appeared in a variety of responses indicates atrioventricular block. Conclusions The different responses during RFCA of the slow path for atrioventricular nodal reentrant tachycardia should be noted.
