The head-upright tilt-table (HUT) test is used primarily for the investigation of orthostatic symptoms. Although this test is frequently the gold standard for the evaluation of neurocardiogenic syncope, dysautonomia and postural orthostatic tachycardia syndrome, there is a debate over its diagnostic value and method. The authors review the physiologic basis of the HUT test, the method, patterns of response, indications and contraindications, and diagnostic validity. Despite its limitations, the HUT test is useful in patients with a variety of clinical manifestations induced by orthostatism. It is most useful in documenting objective measures of orthostatic hypertension that cannot be obtained in a clinical setting.
头高位倾斜试验(HUT)主要用于直立位症状的检查。尽管该试验常作为评估神经心源性晕厥、自主神经功能障碍和体位性直立性心动过速综合征的金标准,但关于其诊断价值和方法仍存在争议。作者回顾了HUT试验的生理基础、方法、反应模式、适应证和禁忌证以及诊断有效性。尽管存在局限性,但HUT试验对于由直立位引起的各种临床表现的患者是有用的。它在记录临床环境中无法获得的直立性高血压的客观指标方面最为有用。
