You won't be invited back for further diagnostics and more intervention earlier than several months post initial ablation. You'll still need the blood panel and maybe a CT scan again so that your innards can be demonstrably good, or at least that no substantial changes have taken place, such as a tumor or whatever. I don't know the medical system's rules or protocols, but your heart and system need a solid run of healing before the EP will want to start the procedure all over again. Even so, the best person to ask is probably the clerk, or the EP him/herself.
Also, the question by Pompon is à propos. What do you take by mouth that was prescribed post ablation for any remedial or prophylactic effect? Maybe metoprolol will help, but it isn't anti-arrhythmic. It's purpose is 'rate control'. It is more likely that you would be prescribed sotolol, flecainide, or multaq, as the case may be, or Amiodarone if it's indicated and you have a rapid arrhythmia, as I have.
Again, pose the question(s) to those who are caring for you.
