Mayo Clinic treated me 3+ years ago when I was in heart failure. They are great. There are two types of treatments with afib. One is getting the heart back in sinus rhythm. This is done with cardioversion, ablation, and meds. None of them work all the time or for only awhile. I had three cardioversions, none sticked. This is due to my hearts enlargement and heart valve issues I then was downloaded with Tikasen which kept my heart in rhythm for one year. That no longer worked, so I went to the second type of treatment.

That's heart rate control. I was put on metotropal (sp), this is a blood pressure med, surpresses the heart rate. It is working for me. All meds have side effects, some better than others. You can look up these issues on the computer; Mayo Clinic has paragraphs you can read online on most medical issues. Best of luck, if it makes you feel any better, afib is very common. The biggest problem with it that it can cause strokes, so an anticoagulant is prescribed, such as Eliquis. It's an expressive medicine, but does a good job.
