Key result
In patients with dual-chamber pacemakers and no prior history of atrial fibrillation, the incidence of atrial high-rate episodes was 13.19% over 12 to 18 months, significantly predicted by advanced age and higher systolic blood pressure.
Why the study?
Paroxysmal AF is often asymptomatic and risks delayed diagnosis, but dual-chamber pacemakers enable continuous rhythm monitoring to detect subclinical AF and identify clinical predictors of its development.
Population
91 patients from the Oltenia region receiving dual-chamber pacemakers with no prior AF history
Design
Retrospective cohort study
Follow-up
12 to 18 months

May warrant closer AHRE surveillance in older hypertensive pacemaker patients; hypothesis-generating for anticoagulation trials.
Cohort (n=91)
No
Continuous monitoring via dual-chamber pacemakers detects subclinical atrial fibrillation (AHRE) in approximately 13% of patients without prior AF, particularly in older patients with hypertension.
Negroiu et al. (2024) conducted a cohort in Indications for permanent cardiac pacing without prior atrial fibrillation (n=91). Dual-chamber pacemaker implantation was evaluated on Incidence of atrial high-rate episodes (AHRE). In patients with dual-chamber pacemakers and no prior history of atrial fibrillation, the incidence of atrial high-rate episodes was 13.19% over 12 to 18 months, significantly predicted by advanced age and higher systolic blood pressure.
