Hi Muggles,
I am sorry to hear about your husband. Unfortunately, I cannot answer all the questions -- full understand of tikosyn and amiodarone is way beyond the scope this forum.
I will tell you that we use amiodarone for ventricular arrhythmias more often than atrial arrhythmias. It is efficacious for both, but the side effect profile amiodarone pushes us to use other medications s first line (sotalol, tikosyn).
There is a website posted by an electrophysiology fellow at the Cleveland clinic dealing with medical issues. The website is www.askdrwiki.com. The following link goes into detail about tikosyn use:

There is also some information on this site about amiodarone. This is a very technical website intended for physicians, but it may help explain some of your concerns. Posting on the askdrwiki.com site is intended for physicians only so please do not post unless you are a physician.
Tikosyn is a safe medication when used correctly. The main side effect is a low incidence of ventricular arrhythmias. This is not a great concern, especially in patients with ICDs. The medication, like all a fib meds, is intended to decrease the incidence of atrial fibrillation. The unfortunate truth is that some people are difficult to keep out of a. fib. I am not sure if this is your husband or not.
Depending on your husbands age and risk factors, coumadin may be the right choice regardless of whether his a fib is constant or intermittent.
I do agree that being an informed patient is important, but sometimes you do have to trust your doctors. These are not black and white decisions, and as I a sure you know by now, they are sometimes difficult to make.
I hope this helps. Thanks for posting.
