Logan,
About 14 years ago I suffered from WPW. I had an ablation and have been fine ever since. Back then when I would stress, it would definately effect my WPW. The fact that palpitations would increase my stress level even more did not help either. Just try to relax and don't let worrying about this consume your life. Talk with your doctor and ask what is best for you. If he offers the option of an ablation, I highly recommend it.
