倾斜训练预防血管迷走神经性晕厥发生的疗效观察

[目的]探讨倾斜训练预防血管迷走神经性晕厥发生的效果.[方法]将66例倾斜试验阳性、近期多次发作的血管迷走神经性晕厥患者随机分为倾斜训练组、药物治疗组（美托洛尔）和对照组,治疗2周后复查直立倾斜试验并随访.[结果]除2例因心动过缓退出试验外,余64例中倾斜训练组的直立倾斜试验转阴率为86.4%（19/22）、药物治疗组、对照组的直立倾斜试验转阴率分别为25.0%（5/20）、18.2%（4/22）.倾斜训练组与其他两组比较有统计学差异（P〈0.05）,药物治疗组与对照组比较无统计学差异（P〉0.05）.治疗随访半年,倾斜训练组晕厥复发率为9.1%（2/22）,药物治疗组、对照组晕厥复发率分别为40.0%（8/20）、77.3%（17/22）.三组间比较分别有统计学差异（P〈0.05）,但倾斜训练组晕厥复发率最低.[结论]倾斜训练可更好的预防血管迷走神经性晕厥患者的晕厥发生.

Observation of the Effect of Tilt Training in the Prevention of Vasovagal Syncope

[Objective] To investigate the effect of tilt training in the prevention of vasovagal syncope. [Methods]Totally 66 patients with recurrent vasovagal syncope recently and positive head-up tilt table testing （HUTT） were randomly divided into tilt training group, pharmacotherapy group and control group. They were examined again with HUTT after treatment for 2 weeks and followed up. [Results] Two cases quitted for bradyeardia response. The rate of HUTT from positive to negative was 86.4% for tilt training group, 25.0% for pharmacotherapy group and 18.2% for control group. The former had a statistically significant difference with the latter two （ P〈0.05）, but there was no statistically signifi- cant difference between the pharmacotherapy group and control group （ P〉0. 05）. After half a year of follow-up, the relapse rates for tilt training group, pharmaeotherapy group and control group were 9.1 %, 40. 0 % and 77.3 % respectively. There were significant differences among the three groups （ P 〈0.05）, but the relapse rate for tilt training group was the lowest. [ConclusionlTilt training can prevent the occurrence of syncope in patients with vasovagal syncope.
