摘　　要：目的　评价心房颤动 (房颤 )伴长 RR间期患者电复律后房室结功能 ,探讨房颤伴二度房室阻滞的诊断标准。方法　 2 0例房颤伴长 RR间期的患者 ,均在电复律后行心内电生理检查 ,测定房室结功能。结果　除 1例为一度房室阻滞外 ,其余 1 9例房室结功能均正常。结论　房颤伴长 RR间期不应作为临床诊断二度房室阻滞的标准。Objective To assess the atrioventricular node(AVN)function in patients with atrial fibrillation (AF) associated with long RR interval after cardioversion.Methods The AVN function in 20 cases with AF and long RR interval was evaluated in sinus rhythm using intracardiac electrophysiologic studiy.Results The AVN function was normal in sinus rhythm in 19 cases,and one patient had first degree atrioventricular block (AVB).Conclusion This result may imply that long RR interval during AF should not be used as diagnostic criteria for second degree AVB.
