Abstract

A patient with the myasthenic syndrome was investigated with single fiber electromyography (SFEMG). It was found that 35 of 36 potential pairs had increased "jitter" and that 29 of these demonstrated impulse blockings. There was improvement in neuromuscular transmission with higher rates of innervation. Transmission worsened following rest. The SFEMG findings at the motor end-plate level correlate well with the results of repetitive stimulation and in vitro studies.

摘要

对一名患有肌无力综合征的患者进行了单纤维肌电图（SFEMG）检查。结果发现，36对电位对中有35对的“颤抖”增加，其中29对出现冲动阻滞。神经肌肉传递在较高的神经支配率下有所改善。休息后传递功能恶化。运动终板水平的单纤维肌电图检查结果与重复刺激和体外研究结果密切相关。
