摘要

在北美，头部直立倾斜试验（HUTTs）的实际使用情况尚不清楚。这项在加拿大安大略省多伦多进行的单中心回顾性研究报告了2014年至2024年间对1063名赫特人进行的研究。HUTT的使用逐年增加，由于转诊诊断为体位性心动过速综合征（POTS），进行HUTT的人数增加更多。使用晕厥和POTS的特定诊断标准，在2021年1月之后接受检测的两种诊断的患者，HUTT阳性的几率降低了近50%（晕厥：优势比：0.54,95%可信区间：0.40-0.73，体位性站立性心动过速综合征：优势比：0.51,95%可信区间：0.28-0.95）。

The Evolution of Head-Upright Tilt-Table Testing in Toronto, Ontario, Canada: 2014-2024

The real-world use of head-upright tilt-table tests (HUTTs) in North America is not known. This single-centre retrospective study in Toronto, Ontario, Canada reports on 1063 HUTTs conducted between 2014 and 2024. Use of the HUTT increased year over year, with a greater increase in HUTTs conducted as a result of a referral diagnosis of postural orthostatic tachycardia syndrome (POTS). Using specific diagnostic criteria for syncope and POTS, patients with either diagnosis who underwent testing, after January 2021 had an almost 50% reduction in the odds of a positive HUTT (syncope: odds ratio: 0.54, 95% confidence interval: 0.40-0.73 and postural orthostatic tachycardia syndrome: odds ratio: 0.51, 95% confidence interval: 0.28-0.95).
