Primary Outcome Measures:
  • Subject Rhythm [ Time Frame: Participants will be followed for the duration of their hospital stay post surgery with an expected average of 7 to 10 days and again at surgical follow up appointment up to 6 weeks. ]
    Measuring change from baseline cardiac rhythm.


Enrollment: 1
Study Start Date: March 2012
Study Completion Date: March 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Amiodarone with cardioversion
If subject converts to normal sinus rhythm following amiodarone no further intervention is taken, if subject remains in atrial fibrillation following amiodarone they are cardioverted.
Drug: Amiodarone
Bolus given 150mg IV, then IV drip 1mg per hour infused for 6 hours, 0.5mg per hour infused for 18 hours.
Other Name: Cordarone
Procedure: Cardioversion
Cardioversion done if atrial fibrillation continues following 24 hour infusion of amiodarone. Cardioversion done following hospital protocol.

Detailed Description:
New-onset atrial fibrillation (AF) after cardiac surgery is a well-recognized phenomenon with significant outcome implications. Incidence after coronary artery bypass grafting (CABG) is estimated at 26-33%, while those undergoing valvular surgery bear a greater burden at 33-49%. Clinical and socioeconomic complications resulting from postoperative atrial fibrillation include an increased risk of death (10%), congestive heart failure (4%), prolonged hospital stays, and increased rate of discharge to care facilities over those who remain in sinus rhythm, (7%). Although a body of evidence exists for electrical or pharmacological cardioversion to sinus rhythm postoperatively, there is a marked paucity in the literature regarding efficacy and outcomes combining the two. More specifically, we seek to evaluate the efficacy of DC cardioversion when combined with amiodarone. Improved outcomes with multimodal cardioversion may decrease the postoperative clinical burden of atrial fibrillation on cardiac surgery patients.
