Sex and age impact prevalence and symptoms of vasovagal syncope: Implications for accurate diagnosis

Syncope is characterized by the transient loss of consciousness followed by spontaneous recovery. The mechanism which underlies this condition is reduced blood flow to the brain [1]. Vasovagal syncope, often termed reflex syncope, is the most common type of syncope [1]. Vasovagal Syncope is caused by the abnormal autonomic reflex to certain stimuli such as pain, micturition/defecation, fear, seeing blood, etc., which results in vasodilation and often times, bradycardia [1].
