Study Summary
This study seeks to assess the effect of apnea (breath hold) during atrial fibrillation (AF) ablation by having all ablations performed under apnea. By prospectively studying the effects of apnea on AF ablation, the investigators wish to demonstrate its feasibility, safety and impact on patient outcomes. This is a prospective study that includes both an apnea arm and a control arm. The subjects who consent to the apnea arm will undergo an atrial fibrillation ablation with periods of apnea. The subjects who consent to the control arm will agree to have their data from their standard of care atrial fibrillation be collected for comparison.
Primary Outcome
Contact force variability: Catheter stability metrics will be calculated as standard deviations of contact forces measured during the course of reach ablation region. Contact forces and their standard deviations will range between 0 and 60 grams.
Interventions
- OTHER Periods of Apnea
- OTHER Control Arm - No Periods of Apnea
