ABSTRACT:
In a heart display system a computer is operable to simulate different selected hearts, each with a different pattern of electrophysiological pathways, which conduct waves of depolarization. The computer determines the conduction in the pattern of pathways of a selected heart in accordance with selected parameters and inputs provided by the operator. In simulating the heart, the computer determines whether a depolarization wave proceeds from one pathway segment to an adjacent segment by examining whether the adjacent segment is polarized or depolarized and determines that the depolarization wave proceeds only if the adjacent segment is polarized. The operation of the simulated heart is displayed by showing an animation of the conduction of the depolarization waves in the pattern of electrophysiological pathways of the selected heart, by an ECG, and by a ladder diagram.
