Dear Heather, thank you for your question. Cordarone is the most effective anti-arrhythmic medication available to treat atrial fibrillation in patients with congestive heart failure. Multiple repeated cardioversions can be done to put someone's heart back into normal sinus rhythm, but the success of repeated cardioversions is improved if cordarone is taken. There are many side effects of cordarone including the tendency to cause rhythm disturbances, thyroid dysfunction, fibrosis of the liver and the lungs, and deposits in the lens of the eye. However, the potential to develop these side effects must be measured against the expected benefit of the medication. Maintenance of sinus rhythm is invariably beneficial for patients with heart failure, so medications like cordarone and cardioversion procedures are necessary to achieve that goal. If you have further questions, I suggest that you speak with her physician.
