Abstract
The representation of cardiac potential fields is fundamentally a five dimensional problem. Three dimensions are needed to define space dependence, one to determine the time coordinate and, finally, the fifth dimensions is for the potential values. In order to reduce dimensionality the torso is assumed to be a cylinder which is cut along a generating line (usually along the right axilla) and is unrolled; it thus becomes flat so only two dimensions are needed to identify a surface point. A further dimension-reducing possibility is offered by sampling in the time domain; in other words the time course of the field formation is represented by a series of instantaneous potential distributions. Thus, finally, the elementary unit to be represented is a two dimensional scalar-scalar function. The display of this is already a routine task in computer graphics.
