I decided to start this thread after my recent experience with flecanide, one of the drugs used to control heart rhythm issues, and reading other recent posts dealing with issues from the same type of medication. Has anyone ever had a-fib/a-flutter and the cardio/surgeon not put them on medication and see if the problem would resolve itself? Since I had no history with a-fib, I thought the cardio should have put me on coumadin but left me off of the flecanide. Then take me off of coumadin if the a-fid goes away after the appropriate period of time. These drugs seem to all have dangerous side affects....is there an issue I am not seeing that would come of them leaving a patient in a-fid for a few months if the patient is on coumadin?
