摘　　要：对１０４例不明原因晕厥患者和１４例健康成人行倾斜试验。６０例（５７７％）不明原因晕厥患者诱发晕厥或晕厥前症状。阳性组中６０％是加用异丙肾上腺素的结果。１４例健康成人仅１例诱发晕厥前症状。倾斜试验诱发晕厥或晕厥前症状时，其平均心率、收缩压、舒张压及平均动脉压较晕厥前显著下降（Ｐ＜００５）。倾斜试验结合静脉用异丙肾上腺素诊断血管迷走性晕厥，阳性率较单纯倾斜试验提高１５倍。倾斜试验需正常人群作对照。To assess the impact of isoproterenol,heart-rate and blood pressure change on the outcome of tile table test,104 patients with unknown syncope and 14 normal persons underwent successive 70°、head-up tile for 60 during infusion isoproterenol.60(57.7%)of the 104 patients with unknown syncope had a test that resulted in syncope or presyncope.Isoproterenol was required to produce syncope or presyncope in 60% of positive tests.1(7.1%) of the 14 normal personal had a test that resulted in presyncope.During syncope or presyncope,the mean heart rate,systolic blood pressure,diastolic blood pressure and mean arterial pressure product each decreased significantly (P<0 05)。The head-up tile table test combined isoproterenol may increase positive results in diagnosis of vasovagal syncope.Our study suggest that population and protocol must be matched.
