Clinical efficacy of low-dose methimazole therapy in patients with subclinical hyperthyroidism complicated by paroxysmal atrial fibrillation / 中华内分泌代谢杂志

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.
