I have Afib along with CAD & today I exercised for about 45 minutes. I try to exercise on a regualer basis, but aftertodays work-out. I could tell I messed up because I felt & feel like I may have over done it because  my heart is just straining to beat, thats the last time I exercise like that,is this normal or is it this possible cause ?I know I need towork-out but now this scares me ???
Hello! Welcome and thank you for asking on Chat Doctor! I carefully passed through your question and would explain that your symptoms seem to be related to coronary artery disease. I would recommend consulting with your attending physician for a careful physical exam and some tests
