摘要
采用倾斜６０度持续４５分钟的普通倾斜试验（ＨＵＴ）和一步法异丙基肾上腺素倾斜试验（ＩＳＯ－ＨＵＴ），以及硝酸甘油倾斜试验（ＮＩＴ－ＨＵＴ）分别对６５例血管迷走性晕厥患者和２０例对照者进行了检查。结果：在５５例患者中ＨＵＴ，ＩＳＯ－ＨＵＴ，ＮＩＴ－ＨＵＴ阳性反应例数分别为４例，１６例，８例，故敏感性分别为７％，３２％，２７％。在２０例对照中ＨＵＴ，ＩＳＯ－ＨＵＴ，ＮＩＴ－ＨＵＴ阳性反应的例数分别为２例，１例，３例。其特异性分别为９０％，９４％，８２％。研究结果表明倾斜试验对血管迷走性晕厥是一种很有价值、安全、易行的诊断方法。在倾斜的同时加用ＩＳＯ．ＮＩＴ均可提高ＨＵＴ的敏感性。
This study was designed to assess the value of tilt table test in diagnosing vasovagal syncope (VVS). Fifty- five consecutive patients with VVS and 20 healthy controls underwent 60 degree Head - up tilt test (HuT), a single-stage Isoproterenol tilt table test (ISO - HuT) or/and Nitroglycerin tilt table test (NIT- HuT) Results: The number of positive cases for HuT, ISO- HuT and NIT-HuT were 4 in 55, 16 in 51 and 8 in 30 patients group compared with 2 in 20,1 in 18 and 3 in 18 healthy control group, Therofore the sensitivity of HuT, ISO- HuT and NIT- HuT was 7%, 32% and 27% , respectively, and the specificity was 90%, 94% and 82%, respectively. HuT is a valuable, safe and feasible method of diagnosing VVS,The use of ISO and NIT could increase the sensitivity of table tilt test, with the same high specificity, NIT-HuT is easy to be accepted becaues of few side effects.
