Hemodynamic Assessment of Essential Hypertension by Radiocardiography and Analog Computer Simulation

Abstract

IN order to understand the pathophysio1ogy of essential hypertension, it is mandatory to know the dynamics of maximum and minimum blood pressure. The difficulty in knowing the hemodynamic pattems in essential hypertension is certainry atthbutable to our lack of knowledge of the influential factors in the natural history and pathogenesis of the disease! In this paper we emphasize the hemodynamic pattern of essential hypertension, and the influence of age on cardiac output and renl blood flow, considering the increase in padripheral resistance which is responsible for the high blood pressure.
