The interval between the onsets of the ORS complex and of the brachial Korotkoff sounds at the diastolic pressure in 23 cases of hyperthyroidism was distinctly shorter, 0.15±0.002 sec (SE), than the interval of 0.21±0.004 sec obtained in euthyroid subjects. Measurement of this interval offers a simple, safe, rapidly obtained index of thyroid function.
