Abstract
Presyncope is often defined as a temporary light-headed or dizzy feeling or a transitory reduction but not loss of consciousness. The presyncope vasovagal response can be triggered by stress, prolonged standing, extreme emotions, or severe pain, it occurs due to a reflex bradycardia and peripheral vasodilation (hypotension). A diagnosis of presyncope is often difficult to make, it can quite easily be confused with other conditions.
