Adenosine Study in Paroxysmal Atrial Fibrillation
In Brief
A Phase 2 clinical trial evaluating Adenosine and Isoproterenol for Atrial Fibrillation. Completed, enrolled 131 participants across 1 site.
Detailed Summary
The purpose of this study is to determine if additional ablation during the first procedure as the result of the ability to medically induce quiet atrial arrhythmias will improve clinical outcome in patients with atrial fibrillation thus decreasing the need for additional ablation procedures.

Interventions
Subject will receive 6-24 mg of intravenous adenosine given rapidly for each PV in order to assess dormant PV conduction. Subjects in this group will also receive isoproterenol to assess inducibility of AF with re-isolation of PVs and targeting non PV sources of AF if necessary.Isoproterenol will be infused through a femoral vein at rates of 5, 10, 15, and 20 μg/min for 2 minutes at each infusion rate.
Isoproterenol will be infused through a femoral vein at rates of 5, 10, 15, and 20 μg/min for 2 minutes at each infusion rate. The isoproterenol infusion will be discontinued upon induction of AF, a decrease in systolic blood pressure to\<85 mmHg, complaints of severe chest tightness, electrocardiographic changes suggestive of ischemia, or upon completion of the infusion protocol.
