Overview
Hill's sign refers to popliteal systolic pressure of more than 60 mmHg than the brachial pressure and is present in patients with aortic insufficiency.
A review of publications of arterial pressure transmission in health and disease did not indicate any physiological basis for Hill's sign. Therefore, Hill's sign may be considered as an artefact of sphygmomanometric lower limb pressure measurement, and appears to be absent in some patients with severe aortic insufficiency.[1]
