目的:探讨左房内径大小及房颤发作时间对房颤转复影响。方法:选取阵发性房颤患者166例,根据左房内径大小分为A组(左房内径<40 mm)、B组(左房内径≥40 mm);A组中根据房颤发作时间分为A1组(房颤发作<48h)、A2组(房颤发作时间≥48 h),B组中根据房颤发作时间分为B1组(房颤发作<48 h)、B2组(房颤发作时间≥48 h),均给予口服胺碘酮药物转复房颤,观察房颤转复成功率。结果:A组房颤转复成功率明显高于B组(P<0.01),有统计学差异。A1组较A2组、B1组较B2组房颤转复成功率明显增高(P<0.05)。结论:左房内径大小及房颤发作时间对房颤转复有明显影响。
Objective: To investigate the effect of atrial fibrillation on the size of left atrium and the duration of atrial fibrillation. Methods: A total of 166 patients with paroxysmal atrial fibrillation were divided into group A (left atrium internal diameter <40 mm) and group B (left atrial diameter ≥ 40 mm) The patients in group A1 (group A <48 h), group A2 (group A> 40 h), group B (group B) (group A <48 h), group B Time ≥ 48 h), were given oral amiodarone drug to atrial fibrillation, the success rate of atrial fibrillation was observed. Results: The success rate of atrial fibrillation in group A was significantly higher than that in group B (P <0.01), with statistical difference. A1 group than the A2 group, B1 group than B2 group atrial fibrillation success rate was significantly increased (P <0.05). Conclusion: The size of left atrium and the time of atrial fibrillation have a significant effect on the recovery of atrial fibrillation.
