ELECTRONIC ANALOG SIMULATION OF THE MAMMALIAN CARDIOVASCULAR SYSTEM, PART 3,

Abstract : This report describes the third model of a series of three elementary, electronic analog computer models simulating the mammalian cardiovascular system. Work on this third model was terminated prior to its completion because of a lack of funds; hence, this report describes the modeling of a complex cardiac function, the only part of the task completed to date. This twochambered 'heart' demonstrates the nervous activity exhibited by the real heart including the roles played by the SA node, the AV node, atrial tissue, and ventricular tissue in establishing heart rate. The effect of cardiac nerve block can be simulated. Provision is also made for simulating strength of contraction. The ultimate goal of this effort is the complex simulation of the entire mammalian cardiovascular system. Work will be resumed if funds become available. (Author)
