Reflex syncope is generally considered a benign condition. It is due to a reflex response (parasympathetic enhancement and decreased sympathetic tone) to several stimuli (e.g. micturition, defecation, prolonged standing, pain, gastrointestinal symptoms) that lead to vasodepression, cardiohinibition or a combination of both. The hemodynamic effect cause systemic hypotension and cerebral hypoperfusion. Types of reflex syncope include vasovagal syncope, situational syncope (e.g. micturition syncope), carotid sinus syncope, and some cases without apparent triggers [1–3].
