Graphic representation of deviations of the cardiac electric field.
The first part of the paper presents a survey of mapping methods in electrocardiography and discusses the present possibilities of graphic representation of individual types of maps of the cardiac electric field (CEF). In the second part of the paper, the authors describe their own method of constructing complete departure maps. The mode of determining the matrix of the departure map surface is given. Four spatial maps--CEF surface, projection of CEF surface, threedimensional departure map, contour departure map--yield in one graphic output the complete departure map. The value of personal computers for diagnostic methods in medicine is being emphasized. The paper is supplemented by graphic outputs performed on the computer EC 1045 and represented by the plotter DIGIGRAF.
