摘要：
目的 研究心脏永久性起搏器植入术后起搏阈值升高患者的临床特点及相关影响因素。方法 回顾性分析我科2014年 6月至2016年5月收治的435例行永久性心脏起搏器植入术患者的临床资料，根据起搏器阈值是否升高分为升高组（37例）及正常组（398例），比较两组患者的临床特点，分析起搏器阈值升高的相关危险因素。结果 与正常组比较，升高组患者的心力衰竭、缺血性心肌病、糖脂代谢异常、甲减发生率明显增高（P<0.05），且起搏阈值升高与上述因素具有相关性（P<0.05）。结论 起搏器植入术后阈值升高考虑可能与心肌纤维化有关。

ABSTRACT: Objective To study the clinical features of patients with elevated pacing threshold after permanent pacemaker implantation surgery. Methods The clinical data of 435 patients treated with permanent pacemaker implantation surgery were retrospectively analyzed. All the patients were divided into elevated group (37 cases) and normal group (398 cases) according to pacing threshold. The clinical features of the two groups were compared, and the related risk factors of elevated pacing threshold was analyzed. Results Compared with the normal group, the incidence rate of CHF, CHD, abnormal glucose metabolism, hypothyroidism in the elevated group were significantly higher (P<0.05), and the above factors were related to elevated pacing thresholds (P<0.05). Conclusion The incidence of elevatedpacemaker threshold in patients treated with permanent pacemaker implantation surgery may be related to myocardial fibrosis.
KEYWORDS: cardiac pacemaker; pacing threshold; myocardial fibrosis
