目的 :探讨直立倾斜试验 (TTT)前舌下含服硝酸异山梨酯 (ISDN)对诊断血管迷走性晕厥的价值。方法 :将 6 0例血管迷走性晕厥患者分成基础倾斜试验 (BTTT)组和ISDN舌下含服激发倾斜试验 (TTT加IS DN)组。结果 :BTTT组敏感性 37.5 % ,TTT加ISDN组敏感性 77.8% ;两组比较差异有显著性意义 (P <0 .0 1)。结论 :TTT前舌下含服ISDN对诊断血管迷走性晕厥有较好的诊断价值
Objective: To investigate the value of sublingual isosorbide dinitrate (ISDN) before vertical tilt test (TTT) in the diagnosis of vasovagal syncope. Methods: Sixty patients with vasovagal syncope were divided into two groups: basic tilt test (BTTT) and ISDN sublingual challenge tilt test (TTT plus ISDN). Results: The sensitivity of BTTT group was 37.5% and the sensitivity of TTT plus ISDN group was 77.8%. There was significant difference between the two groups (P <0.01). Conclusions: The diagnosis of vasovagal syncope may be a good diagnostic value of sublingual TNT before TTT
