What should you do?... I'll tell you what I'd do. Unless you're episodes of SVT are several times a month, or unless they really impact your lifestyle, I'd do nothing... for now. You will most likely find that as you age, your episodes of SVT will increase in frequency. The longer you wait, the more electrophysiology and ablation technology advances. As you know with WPW, there are certain circumstances that make you prone to SCD. BUT..I would think that your during your prior electrophysiology procedure, they should have gathered enough data to determone whether you had this set of criteria that would put you at risk. That fact would possibly change my decision.
