I believe what you're talking about is actually spelled vasovagal syncope. It is a blanket term that refers to a number of causes of fainting. People with vasovagal syncope typically have recurring episodes, and they episodes typically happen because of the same stimulus or set of stimuli every time.

Typical triggers for vasovagal syncope include:

  • prolonged standing or upright sitting
  • Stress
  • any painful or unpleasant stimuli, such as
    • giving blood
    • watching someone else give blood
  • prolonged exposure to heat
  • sudden onset of extreme emotions
  • exposure to heat
  • consumption of marijuana
  • consumption of alcohol
  • nausea or vomiting
  • urination ('micturition syncope') or defecation, meaning excreting faecal matter
  • swallowing ('deglutition syncope')
  • sexual arousal
  • abdominal straining or 'bearing down' (as in defecation)

People with trypanophobia ("injection phobia") may suffer from vasovagal syncope from the sight, feeling, or even thought of a needle.
