Apparatus for predicting Tachyarrhytmien

The invention relates to a device for predicting tachyarrhythmias with cardiac electrical signals of a heart sensing detection means and the detected electrical cardiac signals evaluating evaluation means, wherein said detecting means are connected for transmitting the cardiac signals detected in the evaluation with the evaluation means. The apparatus further comprises circadian time signals delivered time means (5), wherein corresponding circadian time signals are allocated to the sensed electrical cardiac signals and / or other cardiac electrical signals derived from the detected electrical cardiac signals, to the evaluation means (4) coupled to said memory means (6) coupled with circadian normal cardiac data and / or other circadian normal cardiac data and the evaluation means (4) and electrical response signals issuing output means (7), wherein the reaction signals from the evaluation means (4) in response to a comparison of the circadian normal cardiac data with the sensed electrical cardiac signals and / or the further circadian normal cardiac data are generated, and with the further electrical cardiac signals taking into account the corresponding circadian time signals to the output means (7) pass.
