Abstract
That inequalities in the blood pressure and volume of the pulse in the right and left brachial arteries may or may not indicate disease of the aorta or its branches is illustrated by 4 cases. Simultaneous measurement of brachial pressures in 1000 normal subjects showed that a sphygmic inequality of 10 mm. Hg, or more, occurred 439 times in 378 persons; 3/4 of the higher pressures were dextrolateral. Sphygmic inequality without organic disease is probably always transitory, and doubtless occurs in all normal persons; its physiology is not understood. Sphygmic inequality in the brachial or carotid arteries cannot be regarded as a sign of disease of the aorta or its branches unless it can be shown to be permanent.This publication has 1 reference indexed in Scilit:
