I had my aifb ablation exactly three months ago in Boston. I had palpitations for the first month - up to 2-3 hours long, but only to about 110 bpm and even - but they eventually went away. I had a heart catheterization a week ago because of continued chest pain (revealed no blockages). But since then I have been getting momentary palpitations. Less than a minute. Usually no more than a couple of seconds. My doctors don't seem concerned. Anybody deal with these?
