suzanne2019 I was floored when he told me that a good many of his patients with afib are long distance runners, marathoners, bodybuilders and athletes. I'm definitely going to seek a second opinion. Right now I feel bewildered, lost and can't seem to stop crying. I've gone from exercising 5 times a week, including weight lifting to being told not to do anything more strenuous than moderate walking. I've never in my life needed any type of medication. Now I take four. I'm so grateful to have found this site. Thank you so much for reaching out to me. Please stay in touch. It really does help to talk to others who understand.
