定义

反射性晕厥是一种短暂意识丧失,但可自发恢复,并与姿势性张力丧失有关。反射性晕厥是最常见的晕厥形式,可以发生在自主神经功能正常的个体。其机制被认为与腿部血液淤积有关,随后回流到心脏的血液减少,引发交感神经张力增加。据推测,心脏剧烈收缩和心室充盈不足会导致交感神经反射性失调和迷走神经过敏。

Reflex syncope is a transient loss of consciousness with spontaneous recovery and associated with loss of postural tone. Reflex syncope is the most common form of syncope and can occur in individuals with normal autonomic function. The mechanism is believed to be related to blood pooling in the legs followed by reduction in blood return to the heart which triggers a sympathetic tone increase. Vigorous cardiac contractions with an underfilled ventricle are hypothesized to cause reflex loss of sympathetic tone and vagotonia.
