Abstract: The Psycho lo gic al Soci et y of Ireland Mechanism, Triggers and SymptomsVasovagal Syncope (VVS), also referred to as Neurocardiogenic Syncope and Neurally Mediated Syncope, is regularly cited as the most common cause of syncope.In the ESC guidelines, VVS falls within a group of syncope known as Reflex Syncope.This refers to a varied set of conditions in which cardiovascular reflexes that are normally useful in controlling the circulation become intermittently inappropriate, in response to a trigger.There is a drop in heart rate (bradycardia) and blood pressure (hypotension), which reduces blood flow to the brain, and this in turn results in a temporary LOC (Van Dijk, & Sheldon, 2008).A wide variety of conditions can trigger VVS, including physical strain, psychological distress, dehydration, bleeding or pain (Kapoor, 2000).Emotional VVS's may also occur in relation to a threat of injury, the Vasovagal Syncope (The Common Faint): What Clinicians Need to Know
