Abstract
Abstract A cardiographic display for displaying an electrocardiograph heart signal in vector format within a single three-dimensional coordinate system sampled at incremental time intervals and combining the above vector display on the same screen with other displays, e.g., a 12-Lead display. Other embodiments of the present invention comprise projecting the results of the heart vectors onto three planes of the coordinate system which represent the frontal, transverse and sagittal planes while simultaneously displaying the three-dimensional vector display. Still other embodiments comprise combining the three-dimensional with various graphs which show the various changes in magnitude and angle between the heart vectors.
