Description

Participants will be randomly assigned to one of two clinical treatment Arms, both of which are standard care procedures performed in the right atrium (RA): Arm A: Pacing from the Bachmann's Bundle (BB) in the right atrium (upper right chamber of the heart) Arm B: Pacing from the right atrial appendage (RAA - a sac attached to the right atrium) Neither of these treatments are experimental; both are routinely performed by Electrophysiologists in the clinical setting. The purpose of this study is to compare side by side these two treatments and evaluate if one is better than the other. After the procedure, participants will be followed for one year. Medical record data will be collected, and a blood sample will be collected upon enrollment and at one year after implantation. Research-related surveys will be completed at the standard-care 3-, 6-, and 12-month visits.
