Just had an EKG last week found out I'm back having afib again running 138-148. Dr. put be back on a higher dose of Amaradrone and Eliquis 2 times a day. probably looking at another Cardioversion #  and probably a [3rd] Ablation. I am concerned with this last 5 yr. history as to how many times a person can go through the continued treatment. I was told the Amaradrone is some nasty side effects to lungs, liver, and thyroid. They have been taking lung x-ray, blood for liver and thyroid functions. I have noticed the shortness of breath has gotten worse over the last 6 months. So I will find out more in a couple weeks?
