目的:探讨接受DDD永久心脏起搏器患者中无症状性心房颤动(Af)的发生及临床意义。方法:76例安装DDD/R永久心脏起搏器的患者,术后定期随访程控起搏器,记录患者发生Af的次数和持续时间,及发生Af时的症状。结果:17例(22.37%)出现Af,其中无症状性Af 7例,占总Af人数的41.18%。结论:DDD永久起搏器置入后许多患者出现Af,而许多Af事件是无相关症状的,通过起搏器自动模式转换功能可以发现此类患者并进行适当的临床干预。
Objective: To investigate the occurrence and clinical significance of asymptomatic atrial fibrillation (Af) in patients receiving DDD permanent pacemaker. Methods: A total of 76 patients with DDD / R permanent cardiac pacemaker were followed up and controlled by a regular pacemaker. The number and duration of Af patients were recorded, and the symptoms of Af were recorded. Results: Af occurred in 17 cases (22.37%), of which 7 cases were asymptomatic, accounting for 41.18% of the total. CONCLUSIONS: Many patients develop Af after the DDD permanent pacemaker is inserted, whereas many Af events are associated with no symptoms and these patients can be identified by appropriate automatic mode switching of the pacemaker with appropriate clinical intervention.
