1956年 Gamstorp 首次报道周期性麻痹期血钾升高,并命名为遗传性周期麻痹,它是一种在两性中具有高外显率的常染色体显性遗传病,并有三种不同亚型的肌强直高血钾性周期性麻痹(PPⅡ,MIM170500)(1)无肌强直;(2)肌电图和临床有肌强直;(3)肌强直性痉挛。高加索人群肌强直 PPⅡ发病率低。肌强直 PPⅡ的临床症状出现在10～20岁,以运动后偶发性肌无力为特征,麻痹期血钾不同程度升高,通常发作持续不超过数小时,寒冷、饥饿、运动后紧张。富含钾的食物能增加钾负荷可加速发作,在频发
Gamstorp first reported in 1956 elevated serum potassium levels in the periodic paralysis and was named hereditary periodic paralysis, which is an autosomal dominant genetic disease with high penetrance in both sexes and has three distinct subtypes of muscle Hypertrophic Hyperthyroidism Periodic Paralysis (PPⅡ, MIM170500) (1) Muscle-free myotons; (2) EMG and clinical myotonia; (3) Myotonic spasm. Caucasian people myotonia PP Ⅱ incidence is low. Myotonia PP Ⅱ clinical symptoms appear in 10 to 20 years old, characterized by occasional muscle weakness after exercise, hyperkyleneuria in different stages of paralysis increased, usually for no more than a few hours, cold, hunger, tension after exercise. Potassium-rich foods can increase the load of potassium can speed up the attack, in the frequent
