arterial compliance was determined in eight normal subjects and 23 patients with hypertension and vascular disease by two independent techniques : ( a ) with a plethysmographic strain gauge ( to measure pulsatile forearm volume changes as representing intra-arterial volume changes ) and an automated sphygmomanometric system ( to measure pulse pressure ) and ( b ) calculation from the local pulse wave velocity and dimension of the brachial artery measured by pulsed wave doppler ultrasound .
