Abstract

A modified Windkessel model was used to investigate interactions between peripheral resistance and ejection fraction in determining hypertension. Experimental aortic pressure, Pa(t), and aortic flow, Qa(t), data from mongrel dogs with an average of 23 kg were digitized and then incorporated into a three-element lumped arterial system model. By manipulating peripheral resistance (Rs), systemic capacitance (Cs), and Qa(t), the Pa(t) was studied. Results indicated that elevated Pa(t) caused by increased ejection fraction (EF) can be observed within normal or reduced peripheral impedance. Thus anti-hypertensive drugs using vasodilator could not be effective if cardiac origin of hypertension is involved.
