Radiofrequency Ablation of Atrial Fibrillation Under Apnea

Radiofrequency Ablation of Atrial Fibrillation Under Apnea

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.

Inclusion Criteria:

• Age 18 - 80 years old.
• Symptomatic paroxysmal atrial fibrillation.

Exclusion Criteria:

• Patients with persistent or permanent atrial fibrillation or prior atrial fibrillation ablation.
• Significant chronic obstructive pulmonary disease (such as those requiring home oxygen).
• Severe pulmonary hypertension.
• Other intrinsic lung pathology such as interstitial lung disease.
• Severe systolic dysfunction defined as left ventricular ejection fraction < 30%.
