Atrial Contractions

dracomullet asked:

I have intermitent rapid atrial fibrulation, my electrphysiologist wants me to have a heart ablation when the go in an kill the part of your heart that is misfiring. I am not sure this is the way to go since my condition is intermittant and therefor not predictable. I don’t like that they will be zapping parts of my heart that may be healthy and weakening my heart further. Pros and Cons please.
