Abstract

A 26-year-old man had a loss consciousness for a few minutes while smoking in the standing position, and was referred to hospital. No abnormalities were found in a computed tomography examination of his head, in a 24-h electrocardiogram or in an exercise tolerance test. The head-up tilt test (HUT) while tobacco smoking elicited a positive response in the tilted position, but the HUT without tobacco smoking was negative. The most noteworthy effect of tobacco smoking during the HUT was the high level of plasma epinephrine compared to the levels seen during supine smoking or the HUT alone. Syncope induced by tobacco smoking in the standing position is rare and the mechanism may be the same as that underlying neurally mediated syncope.
平视姿势吸烟引起的晕厥。
一名26岁的男子在站着抽烟时失去了几分钟的意识,并被送往医院。头部计算机断层扫描、24小时心电图和运动耐量试验均未发现异常。吸烟时平视倾斜试验(HUT)在倾斜体位引起正反应,吸烟时平视倾斜试验(HUT)在倾斜体位引起负反应。在HUT期间吸烟最显著的影响是,与仰卧吸烟或单独HUT期间相比,血浆肾上腺素水平较高。站立姿势吸烟引起的晕厥是罕见的,其机制可能与潜在的神经介导的晕厥相同。
