The article examines studies on the use of amiodarone to prevent atrial fibrillation after cardiac surgery and discusses the various regimens for the administration of the drug. In the U.S., atrial fibrillation is the most common arrhythmia after cardiac surgery and is estimated to occur in 10 to 50 percent of all cardiac surgery patients. Atrial fibrillation is attributed to multiple reentry wavelets of excitation that circulate throughout the atria and are triggered by premature atrial contractions. The mechanism of action of amiodarone is also discussed.
