I see your post is a couple of years old now, but wondering if you received the input/answer you were looking for. I too have lone a-fib and have had rf abalation to correct it. I have been mostly symptom free for a year and a half now. I also want to get back into diving but can't seem to get a straight answer from my doctor. Are you diving again? What advise and or direction have your doctor's givin you?
