Hi bandit, It is good to be informed about
the possibilities but just remember that you cant control it. Stressing on it is not going to help anything but make you feel worse. It is a good sign for you that you dont have a family history of heart disease or problems and that you are young. In my case I have an extensive family history of heart defects and disease. I am not sure what the difference in between Atrial Fibrillation and PVC's are without looking them up myself
. And of course I am not a doctor and wouldn't want to try to diagnosis. How soon is your doctor appointment?
