Supports routine post-pacemaker arrhythmia surveillance; extends observational incidence data but leaves open randomized prevention trials.
What is the incidence of arrhythmias after atrial or dual-chamber pacemaker implantation in patients without preexisting atrial tachyarrhythmias?
The incidence of atrial fibrillation or flutter after dual-chamber or atrial pacing in patients without prior atrial tachyarrhythmias is moderately low (8.9% at 22 months) and generally manageable with medical therapy.
Jordaens et al. (1989) studied this question.
