I was in good shape when I got A-fib and it is like you describe. I had ridden a 57 minute 40k and a few weeks later I could not jog to the end of the block, literally. Has an ablation in September and KQ'd in March. The surgery sucks just like any surgery but it works, go the best guy, not some doc your primary suggests.Don't put it off A-fib does not cure itself ever, and the drugs for it are lame if you want to be active.
good luck dude, find the best doctor and one who understands you want to train.
The holter is worth a try but may not pick anything up.
