What do you suggest if I put on rythmol (propafenone) to convert back to nsr. Echo showed no problems, any idea how long to get out of a fib?

Atrial fibrillation. Rhythmol is a drug that can be used to prevent or convert atrial fibrillation. There is no good way to predict if it will convert the rhythm and/or predict how long it will take. In general, however, if its going to work at the dose being given, it will generally take less than a day to convert.
