I agree about going to an EP, who is a specialist in the electrical part of the heart. Some can have their episodes completely controlled by meds, others not. Since an ablation is an invasive and very expensive procedure, I would try the meds first. I was on Verapamil for 5 years for my SVT and had no side effects and no episodes, plus it controlled my zillion PVC's. You may have to try more than one med. How often are your episodes and how high does your rate get? I really doubt that you will outgrow it! Just beware of an EP who wants to jump immediately to ablation, as there are some inexperienced ones who want the practice and are anxious to just get in there and play around. Ask how often they have to do a second ablation. My EP said the only time he had to go back sometimes was for a complicated atrial flutter.
Personally, I would get a second opinion with an electrophysiologist.
