Severe auto-immune hypothyroidism, probably after hyperthyroidism, was diagnosed in a 79-year-old woman with hypothyroidism (T3 and T4 immeasurably low) without the classical signs of myxoedema heart. On carotid sinus pressure transitory first degree AV block occurred and, on one occasion, complete AV block. This response disappeared after substitution treatment for four weeks with 50 microgram L-thyroxine. Further examination half a year later, on a maintenance of 75 microgram thyroxine, also gave a negative response to carotid sinus pressure.
一名79岁患有甲状腺功能减退症（T3和T4低至无法测量）的女性被诊断为严重自身免疫性甲状腺功能减退症，可能继发于甲状腺功能亢进症，且无黏液性水肿性心脏病的典型体征。对其进行颈动脉窦按压时，出现了短暂的一度房室传导阻滞，并有一次出现了完全性房室传导阻滞。在用50微克左甲状腺素替代治疗四周后，这种反应消失。半年后，在维持剂量为75微克甲状腺素的情况下再次检查，对颈动脉窦按压的反应也呈阴性。
