Cardiovascular responses to acceleration stress: a computer simulation

Article Abstract:

A mathematical model of the cardiovascular system, developed using engineering methodology, is described. The basic model, which can predict the effects of acceleration stress on peripheral and central vision, has been expanded to include simulations of the heart, arterial, and venous systems, physiologic compensatory mechanisms, and the effects of protective devices and maneuvers. The model facilitates understanding of cardiovascular responses to acceleration stress, mechanisms, which determine tolerance, and factors that limit pilots' performance, and it has been used to study the relative effectiveness of several acceleration protection methods and devices.

Three-dimensional computer simulation of the cardiac system

Article Abstract:

An integrated approach to modeling the cardiac system, focusing on left ventrile mechanics, perfusion, energetics, and electrical activation, is presented. The approach utilizes both simplified and real geometries. The approach facilitates study of complex cardiac interrelationships, and represents a step toward developing a generalized simulator of the heart.
