Abstract
A detailed psychophysiologic analysis of a vasovagal faint occurring in a “blood-injury-illness” phobic demonstrated that the syncopal episode consisted of a diphasic response. This lends support to the hypothesis that vasovagal fainting in these patients is caused by an overcompensating rebound parasympathetic activation following sympathetic arousal. Treatment and research implications of this finding are discussed.
