Abstract

Background: Permanent pacemaker implantation is an effective treatment for bradyarrhythmias when the cause is irreversible. Objectives: To evaluate the outcomes of bradyarrhythmias treatment with permanent pacemaker implantation. Materials and methods: A randomized clinical intervention study on 55 patients with bradyarrhythmias were implanted permanent pacemakers at Can Tho Central General Hospital in 2022-2023. Results: In 40 patients with sinus node dysfunction and 15 patients with atrioventricular block who received permanent pacemaker implantation, 100% of the cases were accessed to the vein by axillary vein, and 100% of the ventricular lead positions were placed in the right ventricular septum, 87.3% of patients were implanted with a permanent dual-chamber pacemaker. The technical success rate was 100%, and the clinical success rate after 3 months was 85.5%. Patients with permanent 2-chamber pacemaker implantation had a statistically significant improvement in left ventricular ejection fraction as well as a decrease in systolic pulmonary artery pressure after 3 months compared with before implantation (p<0.001). Conclusion: Permanent pacemaker implantation effectively treats bradyarrhythmias with high technical and clinical success and minimum complication.
