Abstract

PURPOSE:To theoretically and directly analyze an intracardiac excitation and to apply the analysis to a diagnosis, by constructing a minute three-dimensional myocardial model for exactly reproducing an electric phenomenon occurring in a heart and by simulating a myocardial excitation-propagation and its recovery process. CONSTITUTION:Various cardiac conditions are simulated by altering a basic cardiac model by a means of geometrically changing a cardiac model construction 1, a means of changing a waveform of a myocardial action potential 2 and a means of changing the ratio of a propagation velocity of a special myocardium 3 to that of a heart myocardium and by altering a cardiac barning model memory means 4 by a means of changing a barning condition 5. The basic cardiac model includes many myocardial cells, all of which are calculated by an excitation wavefront processing means 6. A body surface potential processing means 7 divides the cardiac model into an appropriate number of blocks and calculates a body surface potential from the mean dipole value of each block. In the above manner, a diagnosis of an abnormal part, an analysis of the relation between each cardiac part and a coronary symptom and a reproduction of various cardiac conditions are easily attained.
