目的分析亚临床甲亢并周期性瘫痪的临床特点。方法测定总T3、总T4、游离T3、游离T4、促甲状腺素,并回顾分析8例亚临床甲亢并周期性瘫痪的临床资料。结果青壮年男性发病,低钾型周期性瘫痪为主要临床表现,无明显甲状腺功能亢进症表现,测定总T3、总T4、游离T3、游离T4正常,促甲状腺素下降,补钾治疗有效。结论青壮年男性亚临床甲亢的主要临床特点是低钾型周期性瘫痪。

Objective To analyze the clinical characteristics of subclinical hyperthyroidism with periodic paralysis, Methods The thyroid gland functions were examined. The items contained total triiodothyroxin（TT3 ）, total thyroxin（TT4 ）, free triiodothyroxin（FT3 ）, free thyroxin（FT4） and thyroid stimulating hormone（TSH）, and the data of 8 cases of subclinical hyperthyroidism with periodic paralysis were analyzed and summarized. Results The subclinical hyperthyroidism with periodic paralysis was occurred in young man. The main clinical manifestation was hypokalemic periodic paralysis. There were no clinical manifestations of hyperthyroidism. The level of TT3, TT4, FT3 and FT4 were normal, while TSH was decreased. Supplying with kalium was effective. Conclusion The main clinical features of subclinical hyperthyroidism in young men were hypokalemic periodic paralysis.
