No Afib Until Pacemaker

I was walking 2 miles per day until I got a pacemaker installed. I was told that I needed it because of my bradychardia, but as soon as I got the pacemaker I was on Afib (had never been diagnosed with it previously). By "as soon as" I mean while still in the recovery area. To be honest, I now regret getting the pacemaker as I now can barely walk a quarter of a mile or do simple shopping, My best days now are far worse than my worst days before.

I was also diagnosed with atrial flutter and am taking Eliquis and Amniodorone. I am scheduled for an ablation next week and am wondering what to expect. If this makes me feel even worse or weaker I don't know what I'll do, I am hoping to at least be off the Amniodorone as I suspect that it is causing severe vision problems. I am not aware that I am having any side effects from the Eliquis, but I am not sure that it isn't contributing to my lethargy and fatigue.

Any comments are welcome.
