Tilt-table testing has become an important part of the evaluation of patients with unexplained syncope, although not every patient with vasovagal syncope requires it. Studies have attested to the effectiveness of the technique for providing direct diagnostic evidence of a patient's susceptibility to vasovagal syncope. This article reviews the need for tilt-table testing and the recommended methods for performing a test. In addition, a detailed classification of the hemodynamic patterns of collapse displayed over the course of a tilt-table study is provided. These distinctive collapse patterns document the evolution of a syncopal event and are particularly important to identify because they can influence the selection of therapy.
倾斜试验已成为不明原因晕厥患者评估的重要组成部分，尽管并非每个血管迷走性晕厥患者都需要进行此项检查。研究证实了该技术在为患者血管迷走性晕厥易感性提供直接诊断证据方面的有效性。本文回顾了倾斜试验的必要性以及推荐的试验方法。此外，还提供了倾斜试验过程中所显示的晕厥血流动力学模式的详细分类。这些独特的晕厥模式记录了晕厥事件的发展过程，因其会影响治疗方案的选择，故而识别它们尤为重要。
