ABSTRACT:
An apparatus and method for displaying a time history of a vectorcardiogram. The method enables a clinician to create a history of a three-dimensional vectorcardiogram from an arbitrary time axis and over an arbitrary time range. The apparatus allows the clinician to select a given viewpoint axis from a plurality of selectable viewpoint axes as well as the period of history to be displayed. The apparatus can also display multiple time histories simultaneously on the same display. This allows the display, side by side, of a traditional vectorcardiogram and the same vectorcardiogram as viewed from an arbitrary axis or time. This also enables the clinician to view a vectorcardiogram from various viewpoints simultaneously.
