I am waiting for my 3rd ablation and have been advised that if this is not successful this will be the end of the road for my treatment by ablation. I asked what would be the next step and was told that it would be ablation of my natural pacemaker and the insertion of a mechanical pacemaker. I have read up on pacemakers therefore and find that thousands are implanted each year very successfully. My query is why we go through ablations (those of us with intractable AF!) when a pacemaker would be a quicker solution. I feel I am missing something which is probably more complicated! Can anyone please help me with the benefit or their knowledge or experience. I would be very grateful.
