Measure
Conventional Amiodarone Dosing Regimen (CDR)
Initial amiodarone bolus of 150 mg IV over 10 minutes then a 24-hour amiodarone loading infusion (1 mg/min for 6 hours followed by 0.5 mg/min for 18 hours), followed by enteral (400 mg amiodarone oral or per tube three times daily or 2 times daily if the patient has gastrointestinal intolerance when taking the drug three times daily) or intravenous amiodarone (0.5 mg/min continuous infusion) to complete an 8-gm total amiodarone load. Maintenance amiodarone (200 mg amiodarone oral or per tube once daily) at discretion of attending physician. AMIODARONE: Assess the effectiveness of different dosing strategies of amiodarone.
Repeated Amiodarone Bolus Dosing Regimen (RBDR)
Initial amiodarone bolus of 150 mg IV over 10 minutes, then 1.0 mg/min IV amiodarone infusion for 6 hours, then a 0.5 mg/min IV amiodarone infusion for 18 hours, followed by enteral (400 mg amiodarone oral or per tube three times daily or 2 times daily if the patient has gastrointestinal intolerance when taking the drug three times daily) or intravenous amiodarone (0.5 mg/min continuous infusion) to complete an 8-gm total amiodarone load. In addition, patients in the RBDR will receive an additional 150 mg IV amiodarone bolus whenever the patient develops tachycardia (Heart Rate (HR) = 110 beats per minute) lasting more than 10 minutes. This bolus may be repeated up to a total of 5 times (6 total boluses) over the first 24 hours. Maintenance amiodarone (200 mg amiodarone oral or per tube once daily) at discretion of attending physician. AMIODARONE: Assess the effectiveness of different dosing strategies of amiodarone.

PRIMARY outcome

Timeframe: 24-hours after receiving amiodarone bolus

Population: No data released because enrollment was three participants, and one group had a singular participant. Therefore, confidentiality of the participant's health information could be impacted if the outcome measures were displayed.for that group with only one participant. Additionally, the other group only had two participants, again, release of this information could impact their right to confidentiality.

Percentage of patients who develop stable POAF after non-emergent cardiac surgery, the percentage of patients who have converted to NSR at 24-hours after receiving a repeated amiodarone bolus and loading dose regimen to the percentage of patients who have converted to NSR after a conventional amiodarone IV loading dose regimen.
