Abstract

A process for the electronic long-time monitoring of the heart with EKG lead electrodes fastened to the skin of a patient, in which the signal delivered by these electrodes is digitized and evaluated, the process being characterized by the fact that the EKG signal is evaluated simultaneously on basis of several parameters, that all evaluation signals are stored in the form of histograms, and that furthermore, in case of a signal anomaly determined by the evaluation, this anomaly as well as preceding and following signal sections are permanently stored.
