摘要
目的 :观察永久性心脏起搏器植入患者的心房颤动发生情况及其机制。方法 :随访心脏起搏器植入患者 2 45例 ,其中完全性房室传导阻滞 10 0例 ,病态窦房结综合征 75例 , 度房室传导阻滞 45例 ,双束支传导阻滞 2 5例 ,除外风湿性心脏病及扩张型心肌病。起搏模式 VVI15 5例 ,DDD6 5例 ,AAI2 5例 ,平均随访时间 3.5年 (1～ 6年 )。结果 :2 45例患者中 5 5例发生心房颤动 (2 2 .4% ) ,其中 VVI模式 44例 (2 7.5 % ) ,DDD8例 (12 .3% ) ,AAI3例 (12 % )。三种起搏模式心房颤动发生率分别为 2 8.4%、 12 .3%、 12 %。 VVI起搏房颤发生率明显高于 AAI、 DDD起搏 (P<0 .0 5 )。病态窦房结综合征心房颤动发生率 (2 9.3% )明显高于另三种病因 (2 0 %、 17.5 %、 2 0 % ,P均 <0 .0 1)。结论 :病态窦房结综合征是引起心房颤动的重要原因。起搏模式对房颤的发生有重要影响 。
Objective:The aim of our study was to evaluate the incidence of atrial fibrillation by follow up of 3 5 years in patients with pacemaker and its correlation with the mode of stimulation,and the indications for implantation.Methods:Two hundred and forty five patients were studied to assess the incidence of atrial fibrillation.The indication for implant were:complete A V block(100 pts),sick sinus syndrome(75 pts),second degree A V block(45 pts) and bifascicular block(25 pts).The mode of pacing considered were:VVI(155 pts),DDD(65 pts) adn AAI(25 pts).Results:Atrial fibrillation occurred in 55 patients(22 4%).The highest incidence was evidenced in patients with VVI stimulation(28 40%).The incidence of atrial fibrillation in patients with DDD and AAI mode was 12 3%,12% respectively.The incidence of atrial fibrillation in patients with sick sinus syndrome(29 3%) was very high compared with others ( P <0 01).Conclusion:Sick sinus syndrome is a relevant risk factor for atrial fibrillation.The incidence of atrial fibrillation in patients with a pacemaker seems to be dependent upon the mode of stimulation.The presence of retrograde V A conduction and dilated atrial cavity may predict the occurrence of the atrial fibrillation.
