- 摘要:
- 目的: 探讨房室结折返性心动过速射频消融术后复发原因。方法: 对356 例房室结折返性心动过速患者射频消融术后进行随访,回顾性分析其电生理资料。结果: 356例中10例复发,复发率2.8%，320例患者射频术后无心房回波，无跳跃现象，一直未复发；术后有心房回波无跳跃现象未诱发出室上速17例，其中3例复发；术后有跳跃及心房回波未诱发出室上速11例，其中5例复发；术后有跳跃无心房回波未诱发出室上速8例，2例复发。10例复发患者，第2次射频消融术后房室结不应期均较第1次术后延长，且与术前快径不应期差值明显减小，第2次射频消融术后随访至今（>9个月），无1例复发。结论: 慢径残存是房室结折返性心动过速射频消融术后复发的主要原因。
- Abstract:
- AIM: To investigate the cause of atrioventricular nodal reentrant tachycardia (AVNRT) recurrence after slow pathway radiofrequency catheter ablation (RFCA). METHODS: Three hundreds and fifty-six cases with AVNRT after RFCA were followed up and their electrophysiologic data were retrospectively analyzed. RESULTS: Ten of the 356 cases had recurrence (2.8%). No recurrence was observed in the 320 cases without an atrial echo and jump phenomenon after RFCA. Three cases recurred from the 17 cases with an atrial echo but no jump phenomenon in those where no supraventricular tachycardia (SVT) was induced after RFCA. Five cases recurred in the 11 cases with an atrial echo and jump phenomenon but no SVT after RFCA. Two cases recurred from the eight cases with jump phenomenon but no atrial echo and no SVT after RFCA. Among the 10 recurrent cases, atrioventricular nodal refractory period (AVNERP) after the second RFCA obviously lengthened compared with that after the first RFCA and the difference between AVNERP and fast pathway ERP obviously diminished. No recurrence was observed in the 10 recurrent cases who had been treated with a second RFCA (>9 months). CONCLUSION: Slow pathway remnant is the main cause of AVNRT recurrence after slow pathway RFCA.
