Abstract：Objective To investigate the stability and safety of domestic pacemaker leads during short term follow-up.MethodsA retrospective study was performed on 23 cases of patients who were admitted and underwent domestic pacemaker implantation from August 2017 to June 2018.There were 23 cases of patients who were implanted 40 domestic active pacing leads, including 17 QM7211-53pacing leads and 23 QM7211-60 pacing leads.The changes of pacemaker lead parameters (P/R wave amplitude, pacing threshold and pacing impedance) were compared during implantation, 1, 3 and 6 months after operation, and complications were analyzed.Results The thresholds of 1, 3 and 6 months after the operation of atrium and ventricle were all lower than those during the operation, and the difference was statistically significant (P＜0.05). The thresholds of 1, 3 and 6 months after the operation of atrium and ventricle were all lower than those during the operation (P＜0.05). At 3 months after surgery, the threshold value reduced significantly (P＜0.05). At 6 months after surgery, the threshold value tends to be stable, and the difference is not statistically significant compared with the threshold value at 3 months after surgery (P＞0.05). Pairwise comparison of P/R wave amplitudes in atrium and ventricle during and 1, 3 and 6 months after surgery showed no significant difference (P＞0.05). There was no significant difference in impedance pairwise comparison between atrium and ventricle during and 1, 3 and 6 months after surgery (P＞0.05). All patients were discharged 3 to4 days after surgery, and the follow-up time after discharge was 6 months.During the follow-up, the patients had no complications such as pacemaker bag infection, electrode dislocation, electrode perforation, pacemaker syndrome, and no death or re-hospitalization occurred.Conclusion The performance of domestic pacemaker electrode leads is good.In the short-term follow-up after implantation, the parameters are stable, there are no complications, and the safety is high, which can be used as one of the options for clinical application.
