SVT after catheter ablation?

I had a catheter ablation seven weeks ago, due to SVT. I was told it was a success and that I only had a 1% chance for it to come back. Well, since the ablation I have felt wonderful. I got color in my skin I never had, less panicky, ect. I've had maybe 3 skipped beats since. Well, Friday night I was watching television and I went into SVT for maybe 10-20 seconds and I've been having a lot more skipped beats since. Is this normal? I'm going to the doctor over it tomorrow, I'm just worried. Do you think it's coming back?
