Hi I have had AFib for about 3 years. I was told that I couldn't have an ablation because my atrium was already too large and it won't work. I also have a slow heart beat. I can't take most of the normal meds because because they slow down the heart all the time, not just when you have AFib. So now they want to do a pace maker (which will not affect my AFib, just the heart rate). Then I can go on the normal AFib meds. I was looking at old posts and some people talked about a pacemaker and then an ablation. Can any one explain that please.
