Conditions
Brief summary
We propose a randomised control trial to explore whether pacemaker programming, specifically an increased atrial pacing rate, can improve atrial fibrillation (AF) outcomes for older patients with concurrent sinus node disease. Participants will be randomised to either an increased atrial pacing rate, or atrial back-up pacing. The primary outcome will be AF burden.
Interventions
This is a randomised control trial for older patients with both atrial fibrillation (AF) and sinus node dysfunction to expore whether pacemaker programming can decrease the risk of AF recurrence following catheter ablation. All patients will recieve catheter ablation for AF. Patients in the intervention arm will have their pacemaker programmed to a higher atrial pacing rate - termed "increased atrial pacing" (Dual-chamber rate-modulated (DDDR) at 70bpm for all patients in the intervention arm) which will be reprogrammed by the study investigators at the randomisation visit. Patients will be followed up at 3, 6, 9 and 12 months post randomisation, where data from the pacemaker can be reviewed to check adherence to the intervention
