目的评估持续性心房颤动射频导管消融(下称消融)术中房性心动过速是否消融终止对预后的影响.方法持续心房颤动行分步法消融术中转为房性心动过速的患者86例,43例继续消融终止房性心动过速(消融终止组),43例消融不能终止房性心动过速而行电复律(未终止组).随访2年,比较两组房性快速性心律失常的复发率.结果消融术后维持窦性心律55例(63.95%),房性快速性心律失常复发31例(36.05%).复发率消融终止组(27.91%)与消融未终止组(44.19%)比较,差异无统计学意义(P >0.05).左心房前后径窦性心律组[(41.78±7.95)mm]小于复发组[(45.85±8.51) mm],差异有统计学意义(P<0.05).结论持续性心房颤动消融术中房性心动过速能否消融终止不影响房性快速性心律失常的复发.

Objective To evaluate whether ablation of atrial tachycardia(AT) during persistent atrial fibril ation(AF) ab-lation wil influence the prognosis. Methods AT occurred in 86 AF patients underwent a stepwise approach ablation. Of them, AT was terminated by ablation in 43 cases (termination group) and only by electrical cardioversion rather than abla-tion in another 43 cases (non-termination group). The recurrence of atrial tachyarrhythmia (ATa) was determined and compared between the two groups during fol ow-up of 2 years. Results 55 cases (63.95%) maintained sinus rhythm and 31 cases(36.05% ) had recurrence of ATa. The recurrence rate of ATa was 27.91% in termination group and 44.19% in non-termination group. There was no significant difference between the two groups. Left atrial dimension was significantly smal er in patients with sinus rhythm (41.78±7.95mm)than with recurrence of ATa (45.85±8.51mm) (P<0.05). Conclu-sion Whether AT terminated by ablation or not during persistent AF ablation does not influence the recurrence of ATa.
