I had WPW until I had it ablated in 1996. Mine was pretty bad, I ended up in the ER A LOT growing up, especially in adolescence. Having an ablation was the best thing I have ever done. Afterwards, I was able to have caffeine, exercise, etc all the things that would trigger my SVT beforehand. I think my case was fairly serious which is why they suggested I have the ablation (twice bc the first was unsuccessful). I was experiencing arrhythmias quite often. I know that a lot of people can live without being treated for it at all. If never get SVT episodes, or passing out, etc, I would get a second opinion. My cardiologist now said that even one episode a year is NOT grounds for having an ablation. Have they prescribed a beta blocker for you?
How did they discover that you had WPW??? I just met someone I work with whose daughter is 35 and she also just found out she had WPW. Im trying to help her through it, its scary. If you have any other questions, feel free to ask me.
