摘要
目的 探讨舌下含化硝酸甘油倾斜试验对诊断血管迷走性晕厥 (VS)的价值。方法 42例血管迷走性晕厥病人 (VS组 )及 2 0例无晕厥史健康人 (对照组 )先行基础倾斜试验 (BTTT) ,阴性者再做舌下含化硝酸甘油倾斜试验 (SNTTT)。结果 BTTT阳性诱发率 VS组为 2 4% (10 / 42 )对照组为 0 ;两组病人无 1例发生体位性低血压。 VS组和对照组 SNTTT阳性诱发率分别为 47% (15 / 32 )、10 % (2 / 2 0 ) ,药物诱发体位性低血压发生率分别为 12 .5 %、10 % ,两组病人仅有 1例出现头痛 ,但能坚持试验。结论 SNTTT对 VS具有较高的敏感性和特异性 ,副作用小 ,操作简便省时 ,是一实用的检查技术。
Objective To determine value of head-up tilt table test with sublingual nitroglycerin for the diagnosis of vasovagal syncope.Methode 42 patients with vasovagal syncope and 20 subject in control group were studied,The patients and the subjects in the control group underwent baseline tilt table(BTTT).If positive response did not occur,Sublingual nitroglycerin tilt test(SNTTT) was underwent.Resuts During BTTT 10 patients(24%) and no controls had a positive response,no patients and controls had a postural hypotension,during SNTTT a positive response occured in 15(47%) patients with vasovagal syncope and 2(10%) controls,After nitroglycerin administration,postural hypotension response was observed in 4 patient(12.5%) and 2 control subjects(10) and only one in this study had side effect of headache.Conclusion These data indicate that SNTTT for diagosis of vasovagal syncope may be a practial clinical technique with highy sensitivity and specifcity and little side effect.
