@wayne727, it sounds like you're reading a lot and tackling the steep learning curve of living with a-fib. Good for you. The information you read can be confusing or contradictory because one-size does not fit all.

In this patient information from Mayo Clinic regarding treatment, it also says: "If AFib doesn't get better with medicine or other treatments, a procedure called cardiac ablation may be necessary. Sometimes ablation is the first treatment."

As you mentioned, you are feeling fatigued. I would mention this to your cardiologist to determine when the right time for YOU might be for a change in treatment. At the risk of giving you more to read 😐 I found this article by Mayo Clinic experts that might be helpful. It's pretty new and is written for health professionals. It might help you and your care team decide on what and when.

Wayne, when were you diagnosed with AFib? How long have you been taking medication?
