Overview
Brief Summary
The purpose of this study is to determine whether anti arrhythmic medication, specifically Amiodarone, is required during the first three months post surgical ablation.
Hypothesis: Amiodarone will not be required during the first three months as verified by no increase in rehospitalizations for recurrent Atrial Fibrillation, and report of sinus rhythm at surgical follow up (approximately 3 weeks from date of surgery), 6 weeks and 12 weeks to include patients' first follow up with cardiologist at approximately 3 months post surgery.

Outcomes
Primary Outcomes
Change in Status of Rhythm Between Baseline and Follow-Up - Recurrence of Atrial Fibrillation
Time Frame: 3, 6, 12 weeks and 6 months post-procedure
To demonstrate equality in clinically significant recurrence of AF following ablation while showing superiority for complication and side effect rates in those off Amiodarone vs. those on. •% recurrence AF by telemetry at 3 wks and 24-48 hr Holter monitoring at 6 and 12 wks post procedure, EKG at first visit between 6 and 12 wks post discharge and or ER visit for rapid heart rate in atrial arrhythmia requiring treatment; permanent pacemaker interrogation reports at first follow up visit. •Post-procedure major adverse event rate at 6 mos post-procedure related to side effects of Amiodarone.
Secondary Outcomes
- Major Adverse Event Rate(30 days post-procedure)
