摘　　要：目的：探讨甲状腺机能亢进(甲亢)伴发重症肌无力(MG)患者的电生理检测特点,和与慢性甲状腺机能亢进性肌病(CTM)的关系。方法：对7例甲亢伴发MG患者进行神经传导速度(NCV)、重复电刺激(RNS)、针极肌电图(EMG)和单纤维肌电图(SFEMG)检测。结果：7例NCV均正常,RNS 5例异常。EMG 2例发现有肌病的表现,SFEMG均出现jitter增宽。结论：甲亢病人可伴发MG,还可能同时伴发CTM,进行RNS、EMG、SFEMG检测是有必要的。Objective： To explore the electropysiological features of patients with hyperthyroidism and myasthenia gravis （MG）, and the relationship between it and chronic thyrotxic myopathy （CTM）. Methods： Nerve conduction velocity （NCV）, repetitive nerve stimulation （RNS）, electromyogram （EMG） and single fiber electromyogramy （SFEMG） of 7 patients with hyperthyroidism and myasthenia gravis were detected. Results： NCV of 7 cases were normal, RNS of 5 cases were abnormal, EMG of 2 cases has muscle disease, SFEMG of 7 cases had widening the jitter. Conclusion： The patients with hyperthyroidism has often MG, perhaps has CTM. The detection of RNS, EMG and SFEMG of patients with hyperthyroidism are necessary.
