All l can do is wait along with you to see what comes in.
For my part, a person in permanent AFib, I maintain a positive attitude and "believe" the AFib might stop some day...but not because of my attitude. I had heart surgery in November 2007 and the repaired mitral valve has taken the "back pressure" off of my left atrium - thus it is returning to normal size (not as enlarged as it was - doubt it will come back all the way to normal, but each centimeter helps). Or, said another way, while I think a postivie mental attitude helps, I believe AFib is a physical fact and until something changes the electrial signal network to correct the problem, the fibrillation will continue, not necessarily full time, as is my case.
my afib was mostly vagal and I started Yoga a few months back and while I don't know if its the Yoga or all of the other changes I have made, the Yoga doesn't seem to be hurting anything and it's helping me become more "aware" of my body and I'm getting a little more limber and it's helping my posture alot.
I also do pilates and this does'nt seem to bother me either.
I encorporate the meditaion into my Yoga routine at the end of my sessions.
I had chronic a-fib and a-flutter. I would meditate during an episode. It did not prevent an episode, but I did feel it helped the severity of the episode. I eventually had to have an ablation done to prevent my a-fib an flutter.
