None featured actuarial analysis, which is important in a syndrome in which the likelihood of fainting at least once increases with age. Finally, recall bias may be common, particularly in family histories of fainting. Head-up tilt test with clomipramine challenge in vasovagal syndrome-a new tilt testing protocol. Eur Heart J. (2003) 24:658 An episode of vasovagal syncope can sometimes be stopped by immediately doing exercises that tense the muscles. When the muscles are tense, it reduces blood vessel dilation and increases the amount of blood being returned to the heart. Examples of exercises that may help prevent fainting from vasovagal syncope include: Vasovagal syncope (vay-zoh-VAY-gul SING-kuh-pee) occurs when you faint because your body overreacts to certain triggers, such as the sight of blood or extreme emotional distress. It may also be called neurocardiogenic syncope. The vasovagal syncope trigger causes your heart rate and blood pressure to drop suddenly. That leads to reduced blood Summary. Vasovagal syncope is caused by a sudden drop in blood pressure, often triggered by a reaction to something. This causes your heart to slow down for a short time. As a result, your brain Vasovagal syncope, also known as neurocardiogenic syncope or simply "fainting," is a common disorder characterized by a sudden loss of consciousness and muscle tone, typically followed by a rapid recovery.This condition occurs when the body reacts to certain triggers by initiating an exaggerated response of the vagus nerve, a crucial part of the autonomic nervous system. Vasovagal syncope is a common cause of recurrent syncope. Clinically, these episodes may present as an isolated event with an identifiable trigger, or manifest as a cluster of recurrent episodes warranting intensive evaluation. The mechanism of vasovagal syncope is incompletely understood.
