Sorry to hear this Jerry, I know how scary it can be.
My husband was diagnosed with atrial fibrillation when he was 40 years old. He had a history of heart disease in his family, so it was quite a scare. That was 15 years ago and he does great. He takes two pills a day. At first they put him on blood thinners too, because of clots, but he wasn't on them very long at all. It is such a pain getting the blood thinners adjusted. Every now and then (like every 3 or 4 years) he will have a little "spell" and they usually up his medicine to get him through it. We have found that stress definately brings his on, like when his best friend had a stroke, when he was in a vehicle accident, etc. I have never heard of the PVC, hope that doesn't complicate matters too much.
I'm sure you have the best of doctors.
It's hell getting old.
Take care,
Karen
