The upper arm vascular bed investigated by electrical impedance measurement in patients with untreated essential hypertension

Arterial and venous properties of the upper arm vascular bed were noninvasively investigated in hypertensive patients and normotensive controls, using a single method. In patients with essential hypertension the venous and arterial function were both modified. Compared to normotensives, hypertensives showed a decrease of the compliance of the greater arteries and an increase of the compliance of the arterioles.
