In other words, any case when the blood pressure goes down or heart rate decreases might be the clue. Immediately before the person faints, he/she may feel light headed and dizzy, having the blurred vision. Statistics show that the problems appear in 3% of the male population and 3.5% of female population. Thus, both are under the equal risk of vasovagal syncope. Another risk factor is aging.

The symptoms of the reflex syncope may include the skin turning paler, having a light head, blurred vision, rapid changes in body temperature, nausea, being drowsy, lethargy, and excessive sweating. Before fainting, the person may demonstrate several brisk movements of muscles. The seizure may also take place, but it requires a different approach. The pulse of the ‘victim’ is slowing down. The general organism weakness is present too.
