I just wanted to post my experience. Just joined this website - have suffered WPW all my life. 46 yr old healthy female with almost no symptoms (nothing that bothered me, at least) had flutters, palps, vibrations, etc. but did not stop me from caffeine, the gym, sudafed! or anything else until 8 weeks ago. Came on suddenly and fast, within 39 minutes I was at 323 bpm and paremedics had to "cardiovert" me in front of my two children, husband and local police. Holy cow - I realized when I read the ER report how bad it was it said "WPW patient with Atrial Fib near cardiac arrest" - so I had to have an ablation, had my follow up two days ago and I am completely cured. Is that crazy? I almost died? I thought WPW was otherwise harmless but bothersome. I learned differently - the cardiologists and EP's say anyone with WPW should be ablated because it's so inconsistent. My heart rates were fine, and that syndrome lay dormant for over 26 years - I had a small episode in my 20's and was told I had WPW and that people just live with it and it's not life threatening in any way, that is NOT true. Just had to pass this info on....take care all heart patients, especially those with WPW and please ask again if you need treatment. I did and was told to leave things alone as I had no symptons....then 10-17-09 my heart freaked out. God bless....Pam
