摘要
对２１例原因不明晕厥患者（晕厥组）行倾斜试验并以正常人作对照（正常对照组）。晕厥组基础倾斜试验阳性９例（４２．９％），多阶段异丙肾上腺素－倾斜试验阳性１０例（８３．０％），总阳性率为９０．５％（１９／２１）。对照组基础倾斜试验无一例阳性，与晕厥组比较，Ｐ＜０．００１；多阶段异丙肾上腺素－倾斜试验有２例为阳性，假阳性率１０％。结果显示：倾斜试验采用倾斜８０°、持续４５ｍｉｎ、异丙肾上腺素用量为４～６μｇ／ｍｉｎ，对不明原因晕厥的诊断，其敏感性为９０．５％、特异性为９０％、准确性为９０．２％。倾斜试验是诊断血管迷走性晕厥、指导临床治疗的一种有价值的方法。
Head up tilt testing (HUT) was performed in 21 patients with syncope of undetermined origin and in the control group.In the study group,positive basic testing was seen in 9 patients (42.9%),positive multistage isoproterenol HUT in 10 patients (83.3%).In the control group,basic testing was negative ( P <0.001),positive multistage isoproterenol HUT was seen in two subjects,false positive rate was 10%.The results indicated that sensitivity was 90.5%,specificity 90.0% and accurativity 90.2% of HUT of tilt 80° lasting 45 minutes and intravenous given isoproterenol 4～6 μg/min in diagnosis of unexplained syncope.So HUT is important technique of differential diagnosis and instructive treatment of angiovagal syncope.
