本文选择初发未治疗的甲亢99例,随机选用心得安、他巴唑单独或联合治疗。于治疗前后观察临床疗效、血清T_3、T_4、rT_3、TSH以及收缩时间间期(STI)和心阻抗图(ICG)的变化。结果三组中以联合组症状控制最好。三组治疗前血清T_3、T_4、和rT_3、均升高,TSH正常。治疗后,联合组血清T_3下降最快,恢复最早;心得安组T_4无变化,另两组下 In this paper, 99 cases of untreated hyperthyroidism were randomly selected and treated with propranolol and metoprazole alone or in combination. Before and after treatment, the clinical curative effect, changes of serum T 3, T 4, rT 3, TSH, systolic time period (STI) and cardiac impedance map (ICG) were observed.

After treatment, the serum T_3 in the combined group decreased the fastest and recovered the earliest. The T_4 in the propofol group did not change, while in the other two groups
