目的观察3830主动固定电极在临床心脏起搏治疗的可行性和安全性。方法选择2008年~2012年在我院植入永久性人工双腔心脏起搏器的患者225例,包括3830主动固定电极组134例和5076主动固定电极组91例。观察两组术中及术后1周、1个月、3个月、1年和3年的起搏参数和相关并发症的发生情况。结果心房起搏参数比较,3830主动固定电极组起搏阈值和阻抗在术中及术后不同时间均高于5076主动固定电极组(P<0.05,P<0.01),感知参数无明显差异。心室电极术中及术后不同时间的起搏参数比较,感知参数差异无统计学意义,阻抗差异有统计学意义(P<0.05,P<0.01),起搏阈值在术中及术后1周差异有统计学意义(P<0.05,P<0.01)。3830组心房电极在心房不同部位的起搏参数比较,差异均无统计学意义。两组术后3年内出现相关并发症的比较,差异无统计学意义。结论 3830主动固定电极在临床心脏起搏治疗中安全可行。
Objective To observe the feasibility and safety of 3830 active fixed electrodes in clinical cardiac pacing. Methods A total of 225 patients with permanent artificial double-chamber pacemaker implanted in our hospital from 2008 to 2012 were selected, including 134 cases of 3830 active fixed electrode group and 91 cases of 5076 active fixed electrode group. The incidence of pacing parameters and related complications in the two groups during operation and at 1 week, 1 month, 3 months, 1 year and 3 years after operation were observed. Results Compared with 5076 active fixed electrode group (P <0.05, P <0.01), the pacing threshold and impedance of 3830 active fixed electrode group were significantly higher than those of 5076 active fixed electrode group at different time points. There was no significant difference in the parameters of pacing between ventricular electrode and postoperative at different time points, the difference of impedance was statistically significant (P <0.05, P <0.01) The difference was statistically significant (P <0.05, P <0.01). There was no significant difference in pacing parameters of 3830 group atrial electrodes in different parts of the atrium. There was no significant difference in the complication between the two groups within 3 years after operation. Conclusion 3830 active fixed electrode is safe and feasible in clinical cardiac pacing.
