Hi Kevin
Things will get better. The first few days are rough for some people.
Welcome to the Bicuspid Valve club!
A-Fib - yea! I didn't know I had one either until I flew to Belgium ready for my BHR surgery and they told me I had a heart murmur. I asked if it would be a problem and they said NO. I was lucky to get a heart echogram for only $50 in Belgium and they told me that it would not bother me until I was 85. I was only 61 then. UGH - by 5 years later I had to have open surgery for a new tissue aortic valve. It has been a-fib since then so don't feel bad. I laid at the Cleveland Clinic for 8 days post heart surgery being in A-Fib. I was suppose to go home on day 2.
Hopefully, it won't bother you any more, but if it does, you need to go to a heart doctor. You have a much larger chance of having a stroke when you are in A-Fib. The heart is churning around like an old washing machine and can throw a clot.
I am not trying to scare you or worry you, but it is better to be safe than sorry. I take warfrin daily and other heart meds to try to keep my heart in normal rhythm. Hopefully it won't bother you much more for many years. It becomes worse as you get older and you are not older yet!
I just thought you would appreciate hearing from someone that has been there and done that with A-Fib
Good Luck and stay in touch when you can. It will get better.
