Abstract：Objective To explore the effect of lead-free pacemakers in the treatment of middle-aged and elderly patients with bradyarrhythmia.Methods A total of 94 middle-aged and elderly patients with bradyarrhythmia who underwent lead-free pacemaker implantation treatment at Meizhou People's Hospital from May 2020 to May 2022 were selected.They were divided into an elderly group(≥60 years old)of 80 patients and a young and middle-aged group(<60 years old)of 14 patients.All patients underwent Micra lead-free pacemaker implantation treatment,and surgical related indicators,changes in pacemaker electrical parameters,and complications were compared between the two groups.Results There was no significant difference in implantation success rate(both 100.00%),surgical time,X-ray projection time,and Micra release frequency between the two groups(P>0.05).During the one-year follow-up period after surgery,the pacemaker threshold,perception,and impedance of the two groups remained within the normal range,with no significant difference(P>0.05).There was no significant difference in the incidence of complications between the two groups(P>0.05).Conclusion Micra lead-free pacemaker implantation is safe and effective in the treatment of middle-aged and elderly patients with bradyarrhythmia,and has advantages,such as short surgical time,high implantation success rate,and good electrical parameter stability.It is worth promoting and using.
