The phase portrait is considered as the brightness image. The image brightness is proportional by number pixels with identical coordinate in a phase spaces. The method give facility for using mathematical apparatus of digital image processing and pattern recognition theories for increasing informativity and validity of multidimensional electrocardiogram analysis. Keywords multichannel electrocardiogram, phase portrait, singular decomposition, brightness image, segmentation References 1. Файнзильберг Л. С.
