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 evaluate the atrioventricular node function after atrial fibrillation (RR) patients with long RR interval and to explore the diagnostic criteria of atrial fibrillation with second degree atrioventricular block. Methods Twenty patients with atrial fibrillation and long RR interval underwent cardiac electrophysiological examination after cardioversion to determine atrioventricular node function. Results In addition to one case of primary AV block, the remaining 19 cases of atrioventricular node function were normal. Conclusions Atrial fibrillation with long RR interval should not be used as a standard for clinical diagnosis of second-degree atrioventricular block.
