Blacked out at Wing Chun yesterday

Weird that it has never happened before. Had a chat with TK about it and he pointed me to this: http://en.wikipedia.org/wiki/Vasovagal_syncope

I saw the first 2 triggers and chuckled. Yup, sounds exactly like Wing Chun class.

Series of events:
  • got into the "hourglass" stance (had been practicing for an hour or two before that)
  • got stance tweaked to the 'correct' form, started hurting more
  • toes pointed in, knees and achilles tense and locked
  • quads near the knee start burning
  • legs tremble
  • achilles tendon is tight, strained and slowly stretching
  • shoulders are stretched tight from having fists in the cocked back position
  • I can feel body weight centered from head to somewhere between the balls of my feet
  • breathing is a little labored as I try to maintain form
  • legs burn, I take deep breaths, inhaling and exhaling to breathe through the pain
  • legs start to fail now, I feel like they are struggling to support my weight
  • I consciously keep breathing deeply, I hear my breath going in and out
  • I feel a little light headed, and I force myself to keep breathing
  • I decide to finally stand up to relieve the pain
  • My vision starts blurring, I mention that I am light headed
  • I remember lowering myself to the ground into a sitting position
  • Memory is fuzzy in this period
  • Next thing I remember is being pulled back to the wall
  • People looking at me concerned
  • I still feel light headed, but I am conscious
  • My vision is blurry. Dark, I still see colors, but everything is like a watercolor painting, or large pixels. I can see shapes and movement, but lights are faint.
  • I can hear people talking to me. Volume is lower, my ears feel a little stuffed
  • I can process thoughts, and respond and converse with people, although my vision is still hazy
  • My vision stays fuzzy for a few minutes. I'm surprised at how long it's taking for my vision to recover, considering that I feel fine now
  • breathing is okay, control and feeling to my entire body has been restored
  • I feel strong again, like I could just get up and run. But I stay seated just in case
  • Eventually I feel tired of sitting down so I stand up. I don't feel light headed anymore. Only thing bad that I feel are my spent leg muscles, which are expected.
  • My vision starts to clear up. The black fuzz dissipates, room brightens and image sharpens
I assess my condition:
  • I have been well hydrated all throughout the day (went to pee 4 times at work, another time before leaving for class. Didn't pee at class, but drank water every half hour or so)
  • I had a normal lunch and had a bagel before class. I did not feel weak or hungry. In fact I felt like I had the energy to run for a couple of miles
