Vasovagal episode - What the heck is that?!?

Yesterday morning I went for my usual Thursday morning swim with the triathlon club. We are lucky, this week the coach decided to start the practice at 6am, so we can sleep in.

After 45minutes or so, I go out of the pool and went to the bathroom. At some point I started feeling really light headed. Five minutes or so later I woke up lying on the ground with blood all over my head. At first I wondered why I fell asleep on the ground, then after a couple of seconds I realized that I passed out and saw the blood on the ground. I went and sit to get my mind back, and started wondering if I should get back to the swimming pool to get help. But since I was full of blood I was not sure it was a great idea.

At that point I saw one guy from the club, and I asked him to go get the coach. After that everything went really fast, the medic got there and checked me. After a couple of testing and all I was in the hospital all plugged in. The doctors were not sure if I it was a problem with my heart so they decided to test me for every possible heart problem. I got like three electrocardiogram to make sure that I had no arrhythmias in my heart.

When they finally got all my results they told me that finally it was a vasovagal episode. http://en.wikipedia.org/wiki/Vasovagal_episode

I got 6 stitches on the top of my head and the doctor told me to always eat before going for a swim, a little bit to make sure I have enough energy. I decided to take a couple more rest days before restarting my training, just in case.
