Abstract: The invention relates to a method and a device for representing and monitoring function parameters of a physiological system, in particular electrocardiographic data, which are derived from electronic measuring signals. The object of the present invention is to provide a method and a device which quickly and in a fashion which can be used by anyone render it possible to analyze the variation in process states and to predict future states. This object is achieved according to the invention by virtue of the fact that the data are combined to form a basic data model and are converted into a graphical portrait which is constructed in the manner of a three-dimensional topological model.
