Electrogram-guided Bachmann bundle area pacing to correct interatrial block: Initial experience, safety, and feasibility
Authors' conclusion
BBAP is feasible in a high percentage of patients and is associated with stable capture thresholds during follow-up.
Study context
- Population
- Patients with baseline interatrial block undergoing dual-chamber pacemaker or ICD implantation
- Participants
- 36 patients
- Outcome
- Feasibility and safety of electrogram-guided BB pacing
