I'm Ken. I'm 81 years old and have had two ablation procedures for atrial fib. The first (October 2011) was unsuccessful. The second (January 31, 2012) destroyed the "atrio-ventricular his bundle", requiring a pacemaker upon which I'm now totally dependent for a heart beat. From the first ablation (October 10, 2012) to the present (April 17, 2012) I've experienced constant burning sensations in my chest. The pacemaker seems to be maintaining the heart rhythm, but the burning continues. A couple members of this forum indicated that their physicians had informed them that sometimes it takes 3-6 months for the pain to discontinue. It's now the sixth month, and the burning has not lessened. I'd like to think that at some point the burning sensations would cease. I suspect that my advanced age has complicated the outcome. Do any of you have any information regarding the experience of other older persons with the ablation? I would greatly appreciate your replies.
