小剂量甲巯咪唑治疗亚临床甲状腺功能亢进症合并阵发性房颤的临床观察

应用小剂量甲巯咪唑+比索洛尔治疗27例亚临床甲状腺功能亢进症合并阵发性房颤患者,治疗前后均接受多普勒超声心动仪、24 h动态心电图检查,放射免疫法测定血清FT3、FT4及TSH,观察期3个月,结果显示治疗后患者左室舒张功能明显改善(P<0.01),窦性心律维持率高,甲减发生率低,提示小剂量甲巯咪唑治疗亚临床甲状腺功能亢进症合并阵发性房颤安全有效.

Abstract：

Twenty-seven patients with subclinical hyperthyroidism(SH)complicated by paroxysmal atrial fibrillation(PAF)were treated with methimazole plus bisoprolol.All patients were examined by Doppler echocardiogram and 24 h ambulatory electrocardiograms before and 3 months after treatment.Serum FT3,FT4,and TSH levels were measured with RIA.The results showed that low-dose methimazole therapy could improve the left ventricular diastolic function(P < 0.01)and help maintain sinus rhythm.The incidence of subclinical hypothyroidism was low.Low-dose methimazole was effective and safe in patients with SH complicated by PAF.
