[Early diagnosis of circulatory insufficiency in thyrotoxicosis].
On the basis of the results of examination of 256 patients with various forms of thyrotoxicosis the author distinguished criteria for early diagnosis of circulatory insufficiency of thyrotoxic origin. The following were referred to their number: a) prolongation of the ejection time with normal or decreased expulsion values; b) increase of the minute heart volume chiefly or exclusively on account of increased frequency of cardiac contractions; c) disproportion between the indices of heart work and the rate of cardiac contraction; d) the presence of hypodynamic reaction to the altering volume load in cardiac fibrillation. Comparison of the mentioned indices with those of clinical symptoms permitted to begin cardiac glycoside therapy in time and to differentiate the therapeutic tactics.
