Physical Counterpressure Maneuvers to Prevent and Abort Vasovagal Syncope: A Novel Effective Treatment?
Vasovagal syncope is a common disorder characterized by reflex vasodilatation and bradycardia, resulting in a drop in systemic blood pressure and diminished cerebral perfusion. The episodes are usually provoked by patient- specific triggers, such as intense emotions or prolonged standing, and are self- limiting . Up to half of the normal population experiences at least one episode of syncope during life. The vast majority of these episodes are of vasovagal origin [2,3].
