目的探讨房室慢旁道的电生理特点及导管射频消融的疗效.方法回顾性分析7例经房室慢旁道逆传的室上性心动过速患者的心脏电生理检查及射频消融的临床资料.结果7例患者电生理检查显示慢旁道只有逆传功能,呈递减性质并伴有文氏现象,心动过速时 RP’> P’R,准确标测慢旁道宜在心动过速时进行,成功靶点应记录最早的逆向 A 波,但 VA 不融合,其间存在等电位线.首次消融术后只有1例复发,再次消融成功后随访无复发,所有病例均无并发症发生.结论房室慢旁道具有特殊的电生理特性,射频消融是安全有效的根治方法.
目的探討房室慢徬道的電生理特點及導管射頻消融的療效.方法迴顧性分析7例經房室慢徬道逆傳的室上性心動過速患者的心髒電生理檢查及射頻消融的臨床資料.結果7例患者電生理檢查顯示慢徬道隻有逆傳功能,呈遞減性質併伴有文氏現象,心動過速時 RP’> P’R,準確標測慢徬道宜在心動過速時進行,成功靶點應記錄最早的逆嚮 A 波,但 VA 不融閤,其間存在等電位線.首次消融術後隻有1例複髮,再次消融成功後隨訪無複髮,所有病例均無併髮癥髮生.結論房室慢徬道具有特殊的電生理特性,射頻消融是安全有效的根治方法.

Objective? To explore the electrophysiologic characteristics of decremental accessory pathways and efficacy of radiofrequency catheter ablation (RFCA) . Method Clinical data of 7 cases with decremental accessory pathways were retrospecively analysed. Results The electorcardiogram in all 7 patients show RP’> P’R during tachycardia. Retrogarde conduction in pathway exhibited decrementa] conduction. The long and separate V A time can be recorded at target site of pathway successful ablationed. The site of earliest reverse A wave in tachycardia is just the target. Conclusion The decremental accessory pathways have special electrophysiologic chatacter.RFCAis an effective and curative therapy for supraventricular tachycardias with decremental accessory pathways.
