Wish there is a way to edit posts ... I meant the following instead.
"AT is different and they should NOT get near the sinus node unless it was an accident."
meant "they should NOT get near the sinus node". I wish the site has an edit feature.
Sorry to hear that you went through that and ended with up a pacemaker at such a young age. I really don't understand why that was done to you when you were asymptomatic and with the risk of heart block so high. AT is different and they should get near the sinus node unless it was an accident.
I had a sinus node modification and my heart rate continued to drop after ablation -- leaving me in a junctional rhythm with pauses while I slept. After a 30 day monitor I was forced to get a pacemaker. My diagnosis is medically induced sick sinus syndrome.
.... I wish I would have waited to have my ablations, but they were actually done after some pre-op testing for a neuro surgery. From what I've read, if you're not symptomatic and have a structurally sound heart, you can put off ablation for benign, atrial rhythms. A lot of people grow out of them.
There are two factors impacting success and complication rates. It depends on the complexity of AT you have and that would range from SVT to atypical (left sided and /or mulitfocal) AT. The other big factor is procedural volume of the EP you are using.
