方法 27例神经心原性晕厥患者入选,女性18例,男性9例,年龄12～75岁。其中17例基础(头高脚低)倾斜试验阳性,另10例在异丙肾上腺素激发后倾斜试验阳性。倾斜试验:患者倾斜70度,倾斜时间最长15分钟。如基础倾斜试验阴性,则仰卧位后静脉内给予异丙肾上腺素,初始注射速率1μg/min,逐渐增快直到心率增加20％,再做倾斜试验。发生低血压同时伴有晕厥或晕厥先兆即为倾斜试验阳性。阳性患者最初3分钟按500μg/kg静注艾司洛尔,此后以300μg/kg/
Methods 27 cases of neuropathic syncope patients were enrolled, 18 females, 9 males, aged 12 to 75 years. Among them, 17 cases had a positive (head-high-foot-low) tilt test and the other 10 cases had a positive tilt test after isoproterenol challenge. Tilt test: Patient tilted 70 degrees, tilt time up to 15 minutes. If the basic tilt test negative, the supine posterior intravenous isoproterenol, the initial injection rate of 1μg / min, gradually increased until the heart rate increased by 20%, do the tilt test. Occurred hypotension accompanied by syncope or syncope aura is positive tilt test. Positive patients received esmolol 500 μg / kg for the first 3 minutes, followed by 300 μg / kg /
