How do pacemakers behave during radiofrequency ablation procedures?
Radiofrequency ablation can cause transient sensing and pacing failures in patients with pacemakers, highlighting the need for generator deactivation and external pacing during the procedure.
Pfeiffer et al. (1995) conducted an observational in Patients with pacemakers undergoing radiofrequency ablation (n=25). Radiofrequency ablation was evaluated on Pacemaker reaction (sensing and pacing failures). Radiofrequency ablation in patients with pacemakers resulted in sensing failures in 32.0% and pacing failures in 16.0%, with no pacemaker damage observed.
