Myxedema
However, the MB fraction in most of these cases is normal, and an electrocardiogram (ECG) often demonstrates bradycardia, low voltage, and loss of T waves that is characteristic[endocrinologyadvisor.com]
Body temperatures as low as 23.3 C have been reported; thus, rectal temperatures are essential to making the diagnosis.[endocrinologyadvisor.com]
In the patient with central hypothyroidism, the diagnosis of myxedema coma maybe very difficult, as serum TSH concentrations will be normal or low.[endocrinologyadvisor.com]
