An expert committee was formed to reach consensus on the use of Tilt Table Testing (TTT) in the diagnosis of disorders that may cause transient loss of consciousness (TLOC) and to outline when other provocative cardiovascular autonomic tests are needed. While TTT adds to history taking, it cannot be a substitute for it. An abnormal TTT result is most meaningful if the provoked event is recognised by patients or eyewitnesses as similar to spontaneous ones. The minimum requirements to perform TTT are a tilt table, a continuous beat-to-beat blood pressure monitor, at least one ECG lead, protocols for the indications stated below and trained staff. This basic equipment lends itself to perform (1) additional provocation tests, such as the active standing test carotid sinus massage and autonomic function tests; (2) additional measurements, such as video, EEG, transcranial Doppler, NIRS, end-tidal CO₂ or neuro-endocrine tests; (3) tailor-made provocation procedures in those with a specific and consistent trigger of TLOC.

TTT and other provocative cardiovascular autonomic tests are indicated if the initial evaluation does not yield a definite or highly likely diagnosis, but raises a suspicion of (1) reflex syncope, (2) the three forms of orthostatic hypotension (OH), i.e. initial, classic and delayed OH, as well as delayed orthostatic blood pressure recovery, (3) postural orthostatic tachycardia syndrome or (4) psychogenic pseudosyncope. A therapeutic indication for TTT is to teach patients with reflex syncope and OH to recognise hypotensive symptoms and to perform physical counter manoeuvres.

成立了一个专家委员会，以就使用倾斜表测试 (TTT) 诊断可能导致暂时性意识丧失 (TLOC) 的疾病达成共识，并概述何时需要其他刺激性心血管自主神经测试。虽然 TTT 增加了历史记录，但它不能替代它。如果患者或目击者认为诱发事件与自发事件相似，则异常 TTT 结果最有意义。执行 TTT 的最低要求是倾斜台、连续的逐搏血压监测仪、至少一个 ECG 导联、以下所述适应症的协议和经过培训的人员。这种基本设备适用于执行 (1) 额外的激发测试，例如主动站立测试颈动脉窦按摩和自主神经功能测试；(2) 附加测量，例如视频，₂或神经内分泌检查；(3) 在那些具有特定和一致触发 TLOC 的情况下量身定制的挑衅程序。

如果初始评估未得出明确或极有可能的诊断，但怀疑 (1) 反射性晕厥，(2) 三种形式的直立性低血压 (OH)，即初始、经典和延迟的 OH，以及延迟的直立性血压恢复，(3) 体位直立性心动过速综合征或 (4) 心因性假性晕厥。TTT 的治疗指征是教会反射性晕厥和 OH 患者识别低血压症状并进行物理对抗。
