Abstract

Rheoplethysmographic studies were conducted to evaluate the digital hemodynamics of the hypertensive state. It is concluded that digital blood flow is similar in normal and hypertensive subjects; digital mean arterial pressures and calculated vascular resistances were significantly elevated in the hypertensive as compared to the normal subject; there is a small but definite increase in digital venous pressure in the hypertensive state; and the digital vasculature and in particular the arteriovenous shunts are otherwise similar in both the normal and the hypertensive subject.
