I was able to get off meds...veeeerrry slowly and carefully with the cardiologist's encouragement, through going to the gym every day. I don't really agree with eileen's in the case of Afib. The heart needs to be pushed into rhythm. Exercise is key. It stabilizes the heart. But if you are ON beta blockers, you will probably feel too tired to do much. So, if you can UP the exercise and DOWN the meds with the doctor's ok, do it! I had the worst case of Afib my cardiologist had ever seen with not even 3 stable beats in a row and I got off the meds over a one month period of daily gym exercise AND avoidance of all stimulants. (chocolate, alcohol, meds with ephedrine for colds or for dental treatments, etc...) Be informed.
