目的对比分析异丙肾上腺素、消心痛激发倾斜试验的敏感性、特异性、耐受性、安全性的差异。方法选择2001年12月至2006年9月于甘肃省金昌市第二医院就诊并符合条件的33例有晕厥发作史的患者及15例无晕厥史者行基础倾斜试验(BTTT),BTTT阴性者连续2d随机进行异丙肾上腺素倾斜试验(ITTT)和消心痛倾斜试验(GTTT)。结果消心痛组敏感性为65.2%,特异性为93.3%,耐受性较好。异丙肾上腺素组敏感性为69.6%,特异性为86.7%,耐受性较差。结论消心痛倾斜试验与异丙肾上腺素倾斜试验比较敏感性、特异性无明显差异,耐受性、安全性好。
Objective To compare the sensitivity, specificity, tolerability and safety of isoproterenol and antihypertensive-induced tilt test. Methods From December 2001 to September 2006 in Gansu Province, Jinchang Second Hospital, eligible 33 patients with history of syncope and 15 patients without history of syncope were based on tilt test (BTTT), BTTT negative The isoproterenol tilt test (ITTT) and the analgesic tilt test (GTTT) were performed randomly for 2 consecutive days. Results Xiao Xiao pain group was 65.2% sensitivity and specificity of 93.3%, better tolerability. Isoproterenol group sensitivity was 69.6%, specificity was 86.7%, poor tolerance. Conclusion Xie Xiao Xie tilt test and isoproterenol tilt test more sensitive, no significant difference in specificity, tolerance, safety and good.
