Objective To observe the incidence and risk factors of postoperative pacemaker complications in elderly（>80 years） patients. Methods A total of 127 elderly patients implanted with cardiac pacemakers were selected from January 2014 to January 2018. The incidence of complications during a 60-day follow-up was observed.Multivariate logistic regression analysis was performed on related factors. Results Of the 127 patients

21（16.5%） had acute complications during follow-up. There was electrode dislocation（n=1

0.8%）

pneumothorax（n=2

1.6%）

local hematoma（n=9

71%）

nerve injury（n=2

1.6%）

subcutaneous emphysema（n=1

0.8%）

venous thrombosis（n=1

0.8%）

pericardial effusion（n=1

0.8%） and postoperative ventricular arrhythmia（n=4

3.1%）. Multivariate logistic stepwise regression analysis showed that women

combined atrial fibrillation

and low body mass index（BMI） were statistically significant for the occurrence of acute complications（p<0.05）. Conclusions The proportion of acute complications after permanent pacemaker implantation in elderly patients is 16.5%

and the related risk factors are women

atrial fibrillation

low BMI. It is necessary to strengthen the treatment and monitoring these patients.
