Four patients with 'syncope' during prolonged head-up tilt testing despite normal blood pressure and heart-rate behaviour are described. They represent 5.5% of all positive tilt-test outcomes from a prospective study of 181 consecutive patients with unexplained syncope. All four patients were female, and were both younger and more symptomatic than patients with vasovagal syncope or orthostatic hypotension. In three of the patients, clinical episodes of syncope were observed which closely resembled those provoked during tilt. It is suggested that the tilt response is psychogenic and reveals a psychiatric cause for recurrent syncope.
本文描述了4例在长时间头高位倾斜试验期间出现“晕厥”的患者，尽管其血压和心率表现正常。在一项对181例连续的不明原因晕厥患者的前瞻性研究中，这4例患者占所有阳性倾斜试验结果的5.5%。所有4例患者均为女性，与血管迷走性晕厥或体位性低血压患者相比，她们更年轻且症状更明显。在其中3例患者中，观察到的临床晕厥发作与倾斜试验期间诱发的发作极为相似。提示倾斜试验反应是心因性的，揭示了反复晕厥的精神科病因。
