[摘要]目的 探讨舌下含服消心痛直立倾斜试验(SISD.HUT)对血管迷走性晕厥(VS)的诊断价值。 方法 对87例晕厥患者(VS组)和40例健康人(对照组)行基础直立倾斜试验(B.HUT)，阴性者再行SISD.HUT，观察倾斜前后血压、心率、十二导联心电图、症状以及服用消心痛以后的变化。 结果 B.HUT阳性诱发率在VS组为24%、对照组为2.5%;VS组和对照组在SISD.HUT中的阳性诱发率分别为56.1%(37/66)和15.4%(6/39);B.HUT和SISD.HUT在VS组中诱发阳性的时间分别是5～27min、平均(19±13)min和2～8min、平均(4±6)min，两组相比有显著性差异(P<0.05);消心痛引起低血压的发生率在VS组和对照组分别为9.1%和7.7%;SISD.HUT诱发VS的敏感性66.7%，特异性是85%。 结论 SISD.HUT对VS的诊断有较高的特异性和敏感性，且方便易行，安全可靠。
