目的探讨起搏器术后新发心房颤动(AF)的发生情况及其相关影响因素。方法:130例病窦综合征或房室传导阻滞植入双腔起搏器患者,分别于术后1年进行起搏器程控随访,记录AF发生例数、累计心室起搏百分比(Cum%VP)、超声心动图参数,按是否发生AF分为AF组和非AF组,比较两组术前和术后有关临床特征。结果新发阵发性AF 45例,85例未发AF,除两组年龄、基础疾病、起搏器型号不同外,其余临床资料基本一致。Cum%VP、左房内径(LAD)、基础疾病、起搏器型号均与起搏器术后AF发生显著相关(r分别为2.545、0.882、-0.799、-1.400,P均<0.05)。结论双腔起搏器植入术后患者AF发生与Cum%VP、LAD、基础疾病、起搏器型号相关。
Objective To investigate the incidence of new-onset atrial fibrillation (AF) after pacemaker operation and its related influential factors. Methods: One hundred and thirty patients with sick sinus syndrome or atrioventricular block were enrolled in this study. The patients were followed up one year after operation by pacemaker program. The number of cases with AF, the cumulative percentage of ventricular pacing (Cum% VP) and echocardiographic parameters were divided into AF group and non-AF group according to whether AF occurred or not, and the clinical characteristics of both groups before and after surgery were compared. Results The new onset of paroxysmal AF in 45 cases, 85 cases of AF, except two groups of age, basic diseases, pacemaker models, the rest of the clinical data are basically the same. Cum% VP, LAD, underlying disease and pacemaker type were all significantly correlated with postoperative pacemaker AF (r = 2.545, 0.882, -0.799, -1.400, P <0.05 respectively). Conclusion The incidence of AF in patients with dual-chamber pacemaker implantation is related to Cum% VP, LAD, underlying diseases and pacemaker type.
