I had atrial fibrillation four years ago, which lead to congestive heart failure. I was taking amlodipine(sp?), digoxin, an metaprolol (200mg). I am now taking just metaprolol (100mg). I feel fine, except with exercise I may get out of breath too soon. My ECG shows no p-wave, somewhat of an irregularity in beat spacing, no spikes in the p-wave segment like there used to be. I had an echocardiogram and my atria are not beating irregularly, in other words they are NOT fibrillating. They have taken me off Pradaxa. But they are recommending an ablation. Do I need this? Will tis help the p-wave? I will see an an ablation specialist in a week.
