     摘要: 目的：探讨三步法直立倾斜试验(HUT) 诊断血管迷走性晕厥(VVS)的可行性。方法：对临床不明原因晕厥的89例患者行HUT，试验分3个步骤，即基础倾斜试验(BHUT)、舌下含服硝酸甘油倾斜试验( SNHUT) 、异丙肾上腺素倾斜试验( IHUT )。结果：89例患者中HUT阳性61例，阳性率为68.54%，其中基础直立倾斜试验阳性13例(14.61%)，舌下含服硝酸甘油阳性44例(57.89%)，含服硝酸甘油阴性的11例中静点异丙肾上腺素阳性4例(36.36%)。结论：三步法直立倾斜试验是诊断血管迷走性晕厥的可行方法。该方法可靠简便，可提高阳性率。

    Abstract: Objective: The result of 89 patients with unexplained syncope in the diagnosis of handup tiltinduced test was summarized. Method: Handup tiltinduced test was carried out in 89 patients with unexplained syncope. First step: baseline handup tiltinduced testing. Second step: sublingual nitroglycerin handup tiltinduced testing. Third step: Isoproterenol handup tiltinduced testing. Result: Sixtyone patients had positive response in 89 patients. Positive rate was 68.53%, 13 patients was positive response in baseline handup tiltinduced testing. 44 patients was positive response in sublingual nitroglycerin handup tiltinduced testing and 4 patients in 11 patients with negative response in sublingual nitroglycerin handup tilt testing had positive response in isoproerenol handup tilt testing. Conclusion: Handup tilt testing is reliaole to diagnose vasovagal syncope and simple. It can raise positive rate. ......
