[Electrolyte metabolism in thyrotoxicosis with energy-dynamic cardiac insufficiency].

In 70 patients with thyrotoxicosis and in 24--with ischemic heart disease with energy-dynamic cardiac insufficiency a study was made of electrolyte metabolism in the blood plasma, erythrocytes and 24-hour urine. The sodium and potassium content in erythrocytes rose, and sodium gradient diminished in the patients examined, this being related to the development of energy-dynamic cardiac insufficiency.
