Abstract: A data management system for processing of physiological or technical data or both to generate a display control signal is disclosed. The data system comprises a data interface having a patient data interface and a user interface. The patient data interface is adapted to receive data which represent physiological parameters of a patient or technical parameters of a medical device, in particular of an implant such as a cardiac pacemaker, defibrillator, or cardioverter, for example. The user interface is adapted to receive data to be entered by a user. The user interface may be a keyboard or a touch screen or a voice interface, for example.
