In high school I first learned about syncope after waking up next to a toilet in an ophthalmologist’s office. He’d just removed some metal from my eye. When I stood up, the room went dim, and somehow my body found itself next to the toilet. I still remember the smell of ammonia and pushing someone away. Luckily, those were the days before syncope… 911… ER.
Later during my residency, I recall standing on one side of a gurney talking with a patient while a nurse was placing an IV on the other, with some young woman behind her. In the corner of my eye I saw what looked like a tree falling… the young woman. It gave me a bit of vertigo, not knowing if I was moving or she. When patient (#2) awoke, she gathered her wits, had a seat, some water, a laugh and recovered just fine.
If you think of your brain as a light bulb and red blood cells as electrons, then “near syncope” = brownout and syncope = blackout. For whatever reason, the electrons just aren’t getting through the bulb. In both cases above, the causes were pretty clear and no call for alarm. Usually the change in position to splayed out flat is therapeutic, as long as it’s a padded landing.
