I was on Pradax, which goes by different names, but it's been deemed dangerous here in Canada because it has no antidote, and my cardiologist feels my condition is improved enough that I'm just on a baby aspirin a day. I've had no more A-fib since the ablation

No - I have not (yet) been diagnosed with A-fib. The doc told me I'm "knocking on the A-fib door".
