起搏部位及起搏模式对术后继发房性心律失常发生的分析

The analysis of the incidence of pacing mode and pacing sites on the occurrence of secondary atrial arrhythmia after operation

目的探讨起搏部位及起搏模式对房性心律失常的影响。方法选取2007年12月-2013年12月于我院行起搏器术后87例患者,患者在术前通过追问病史及相关检查明确排除房性心律失常,平均2.5年的程控及临床随访,对是否有新发房性心律失常患者进行对比分析。结果新发房性心律失常患者共21例(24.13%),归为新发房性心律失常组。其中房颤13例(14.94%),包括阵发性房颤11例(12.64%),持续性房颤2例(2.30%),房速8例(9.20%),其余66例始终保持窦性心律。结论起搏部位、起搏模式等均影响房颤的发生率,心室起搏比例高是术后新发房颤发生的独立危险因素。

Objective To evaluate the incidence of pacing sites and mode on atrial arrhythmia.Methods 87 cases underwent cardiac pacemaker therapy were enrolled in this study.Those patients who had atrial arrhythmia（atrial fibrillation,atrial flapping,atrial tachycardia）before implantation were excluded by learning the history and HOLTER examination from 2007,12 to 2013,12.Results After 2.5years follow-up,there were 21patients（24.13%）with a new atrial arrhythmia,including 13 cases with atrial fibrillation（14.94%）;including 11 cases of paroxysmal atrial fibrillation（12.64%）,2cases with atrial flapping（2.30%）,8cases with atrial tachycardia（9.20%）,the other 66 patients were with non-atrial arrhythmia.Conclusion Pacing sites and mode are affecting the occurrence rate of atrial fibrillation,the high percentage of ventricle pacing is the independent predictors of new-onset atrial arrhythmia after pacemaker implantation.
