摘要：目的：探讨阵发性心房颤动患者植入VVI、DDD起搏器后房颤发作情况的变化。方法：对32例阵发性房颤患者，植入VVI起搏器18例，DDD起搏器14例，比较植入前后房颤发作频率，发作时持续时间的变化。结果：18例应用VVI起搏器患者中3例(16.7%)变为持续性房颤；14例应用DDD起搏器者中3例(21.4%)在未用抗心律失常药物条件下，2例(14.3%)在胺碘酮的应用下，随诊期间维持窦律。其余AF发作次数，发作时持续时间均较前降低>60%。结论:①对于合并缓慢性心律失常的阵发性AF患者，由于起搏器的使用，利于抗心律失常药物选择及控制AF心室率；②DDD起搏器较VVI起搏器更能减少AF发作。

    Abstract：Objective： To investigate the attack of atrial fibrillation changes in the patients associated with paroxysmal atrial fibrillation after implatation of VVI or DDD pacemakers. Method： Among thirty-two patients with paroxysmal atrial fibrillation,eighteen patients were implanted with VVI pacemakers,fourteen patients were implanted with DDD pacemakers The frequence and duration of atrial fibrillation attacking were compared. Result： Three patients (16.7%)switch to persistent atrial fibrillation among VVI pacemakers ,three patients (21.4%)were kept in sinus rhythm in patients who received implanted DDD pacemakers without using antiarrhythmic, two patients(14.3%) who take amidarone were kept sinus rhythm. Atrial fibrillation in frequence and attack duration were shorten more than 60% in others. Conclusion：①Application of pacemakers in patients with paroxysmal atrial fibrillation and bradyarrthymias facilliates the selection of antiarrhythmic drugs and control the rate of ventricular;②DDD is better than VVI in prevention atrial fibrillation. ......
