目的:研究接受DDD永久心脏起搏器患者中无症状性心房颤动的发生及临床意义。方法:47例安装DDD永久心脏起搏器的患者,分别于术后3、6个月随访程控起搏器,记录患者发生心房颤动的次数和持续时间,及发生心房颤动时的症状。结果:术后3个月随访时18例(38.3%)出现心房颤动,其中无症状性心房颤动9例,占总心房颤动人数的50%;术后6个月随访时19例(40.4%)出现心房颤动,其中无症状性心房颤动10例,占总心房颤动人数的52.6%。结论:永久起搏器置入后许多患者出现心房颤动,许多心房颤动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 study the occurrence and clinical significance of asymptomatic atrial fibrillation in patients receiving DDD permanent pacemaker. Methods: 47 patients with DDD permanent cardiac pacemaker were followed up for pacemaker at 3 and 6 months after surgery. The number and duration of atrial fibrillation and the symptoms during atrial fibrillation were recorded. Results: Atrial fibrillation occurred in 18 cases (38.3%) at 3 months after operation, of which 9 cases were asymptomatic atrial fibrillation, accounting for 50% of the total number of atrial fibrillation; 19 cases (40.4%) were followed up 6 months after operation, Atrial fibrillation occurred, of which asymptomatic atrial fibrillation in 10 cases, accounting for 52.6% of the total number of atrial fibrillation. CONCLUSIONS: Many patients develop atrial fibrillation after placement of a permanent pacemaker. Many episodes of atrial fibrillation are associated with no symptoms. These patients can be identified by appropriate pacemaker automatic mode switching and can be given appropriate clinical intervention.
