摘  要:目的探讨直立倾斜试验中诱发晕厥在血管迷走性晕厥(VVS)分型中的意义。方法直立倾斜试验阳性的214例VVS患者按有无发生晕厥分为晕厥组(96例)和无晕厥组(118例),分析两组间及晕厥组内直立倾斜试验时的血压、心率、心律失常、意识丧失和恢复时间及与VVS国际研究分型的关系。结果晕厥组血压值为0/0mmHg、异常心电现象及2B型的发生率明显多于无晕厥组,晕厥组血压下降更明显,2B型发生率更高(均P<0.05)。晕厥组内1型和2型的晕厥发生时间均晚于3型,2型的意识恢复时间长于3型,晕厥组内2型患者晕厥发生时间较晚,意识恢复时间较长(均P<0.05)。结论诱发晕厥作为直立倾斜试验终止指标可增加VASIS分类2B型的发生率。Objective To analyze the value of syncope induced during head-up tilt test(HUTT) in classification of vasovagal syncope(VVS).Methods 214 VVS patients with positive HUTT were divided into syncope group and non-syncope group according to whether syncope was induced during HUTT. Blood pressure,heart rate,arrhythmia,loss of consciousness and recovery time were analyzed in both groups and within syncope group and their relation to Vasovagal Syncope International Study(VASIS) classification were assessed.Results The incidence of blood pressure value 0/0 mmHg,abnormal electrocardiac phenomenon and VASIS classification 2B were significantly higher in syncope group than in non-syncope group. The syncope occurred later in VASIS classification 1 and 2 than VASIS classification 3(all P<0.05). Recovery time of consciousness was longer in VASIS classification 2 than in VASIS classification 3. Syncope occurred later and the recovery time of consciousness was longer in type 2 patients within the syncope group(all P<0.05).Conclusion Induced syncope as a HUTT termination indicator can increase the incidence of VASIS classification 2B.
