I just had ablation for SVT. I have been out of the hospital for one day. I am currently having the same...?

symptoms as before. My doctor said to discontinue the atenolol and that my heart would eventual get back to normal. Well, I can not work with my heart going crazy, plus it feels like I am going to die, so what do I do? Everything that I read says nothing about after ablation feeling the same as before.
