A STUDY ON THE CHARACTERISTICS OF PATIENTS WITH PERMANENT PACEMAKERS IMPLANTED AT CHỢ RẪY HOSPITAL
Main Article Content
Abstract
Objective: To investigate the clinical, subclinical and pacemaker characteristics of patients with permanent pacemaker implantation at Cho Ray Hospital. Subjects and Methods: A cross-sectional study of 134 cases from December 2023 to March 2024 at the Arrhythmia Department of Cho Ray Hospital. Clinical, subclinical, pacemaker type, procedure time and parameter characteristics were analyzed by using R version 4.3.1 (p < 0.05). Results: The most common indications for pacemaker implantation were sick sinus syndrome (33.6%) and atrioventricular block (29.9%). The most commonly implanted device was the dual-chamber pacemaker (61%), followed by ICD (18%), single-chamber pacemaker (12%), and CRT (9%). The median (IQR) time for single-chamber pacemaker implantation was 65 (57.5-82.5) minutes, which was significantly shorter (P < 0.001) than that for dual-chamber pacemaker implantation (90 (70-120) minutes). The two most common pacing modes were DDDR and DDD, accounting for 41.8% and 30.6%, respectively. Conclusions: The implantation time for single-chamber pacemakers was shorter than that for dual-chamber pacemakers. All parameters checked during pacemaker implantation were within acceptable limits. The two most common pacing modes were DDDR and DDD.
