Wow that is scary. Glad you are ok.
I was born with a heart condition called Wolf Parkinson White Syndrome, they didn't discover it until I was about 14. I played soccer, hockey, and baseball through it for years, even when I was diagnosed. I had a 4 hour surgery to correct it when I was 15 and it failed and then I had the same surgery for 8 hours when I was 18 and it was succesful. The reason I decided to have the surgery again was because my heart was beating up to 200 beats per minute for a day and a half and the doctors had to use a defibulator to finally correct it.
