作者报导1例缺氧后动作性肌阵挛(AM)患者的临床和电生理学研究。男,49岁,在主一股动脉搭桥术中发生呼吸意外,昏迷二天后有定向、注意力和记忆障碍,听、体感刺激和近端肌主动活动时出现四肢肌阵挛,以腿运动最易触发。因腿部持久和不规则肌阵挛使患者不能立走,亦影响协调动作。用氯硝安定4天后症状改善,能单独行走,只在站立和急速腿运动时触发轻的短暂肌阵挛。电生理学研究发现:1.缓解期有正常之α节律,F_z—C_z 为持 The authors report a clinical and electrophysiological study of 1 patient with post-hypoxic positoneal myoclonus (AM). Male, 49 years old, had a respiratory accident during an arterial bypass surgery. After two days of coma, there was orientation, attention and memory impairment. Muscle clonus in limbs was most pronounced with hearing and somatosensory stimuli and proximal muscular motility Easy to trigger. Persistent leg and irregular myoclonus due to leg so that patients can not stand, but also affect the coordination of action. After 4 days with clonazepam, the symptoms improved and were able to walk alone, triggering only mild transient myoclonus during standing and rapid leg movements. Electrophysiology study found that: 1. remission of a normal rhythm, F_z-C_z holding
