In 1920, Sturgis and Tompkins1 reviewed the literature dealing with the relation between basal metabolism and resting pulse rate, and reported the results of their own study with special reference to hyperthyroidism. They found that a general parallelism existed between the basal metabolism and the pulse rate. In all but 16 per cent of 154 patients with hyperthyroidism, there was a tachycardia of 90 or more to the minute associated with a basal metabolism of + 15 per cent or more. On the other hand, they found that during complete rest a pulse rate below 90 per minute is seldom found and that below 80 per minute is rarely associated with an increase in metabolism.
Minot and Means2 found that the amount of elevation in the pulse rate for a given elevation in the metabolic rate is essentially the same in hyperthyroidism and in chronic leukemia, and they infer that
