I was told that my SVT that lasted one hour I was lucky it did not do heart damage, I had my ablation in May, of course I was told that they could not get the entire 'short' since it is a short in the electrical system, I get a minor, minor start of the short and it ends, it hits where it was ablated :) If it was me, I would be at the cardiologist, it's a electrical issue, you are not pumping correctly, my beats were 230 and I almost passed out, not pumping blood, seriously look into it.
