A síncope reflexa é uma perda transitória de consciência com recuperação espontânea e associada à perda do tônus postural. A síncope reflexa é a forma mais comum de síncope e pode ocorrer em indivíduos com função autonômica normal. Acredita-se que o mecanismo esteja relacionado ao acúmulo de sangue nas pernas, seguido pela redução no retorno do sangue ao coração, o que desencadeia um aumento do tônus simpático. Supõe-se que contrações cardíacas vigorosas com um ventrículo sub-preenchido causem perda reflexa do tônus simpático e vagotonia. | |||||||||||||||
