Grand mal or la petite morte?

An incident from my time at the hospital:

EMS gets a call that an elderly man has had a seizure and is now unconscious. When they get to the scene the man's wife is freaking out. With a little effort, but the paramedic rouses the old guy. He's fine. Turns out he and his wife were having sex for the first time in 15 years - thanks to Viagra or Cialis I assume - then he sat up too quickly and briefly passed out. Even after a decade and a half, it still seems like his wife should be able to tell the difference between a seizure and an orgasm.
