Glad to hear you are in cardic rehab and are doing very well with it; I found it very helpful in my recovery. Anxiety is normal, hang in there. I haven't taken and of the meds you are on. I've taken diltiazem and eliquis (still on those two), flecainide, and a short course of amiodarone. I have not had any back reactions to any of them.
All the best.
