Two patients with phobias for medical procedures and trauma developed "vasovagal syncope" with hypotension and bradycardia while viewing a videotape of a venous cutdown. Eleven hours of exposure therapy per patient eliminated both the phobic and fainting responses. These facts support existing hypotheses that phobias of this type and vasovagal fainting are associated and that vasovagal syncope is a diphasic response. They do not support hypotheses that vasovagal syncope follows sudden cessation of anxiety, that that counter-conditioning is necessary for successful treatment, or that novel symptoms emerge following behavioral treatment of these phobias.
两名患有医疗程序恐惧症和创伤后应激障碍的患者在观看静脉切开术录像带时出现了伴有低血压和心动过缓的“血管迷走性晕厥”。每位患者接受11小时的暴露疗法后，恐惧和昏厥反应均消失。这些事实支持了现有的假设，即此类恐惧症与血管迷走性昏厥有关，且血管迷走性晕厥是一种双相反应。它们不支持以下假设：血管迷走性晕厥是焦虑突然停止后发生的；反条件作用是成功治疗所必需的；或者在对这些恐惧症进行行为治疗后会出现新的症状。
