Abstract

An automatic implantable device system including an implantable device which communicates with an external programming unit via uplink and downlink telemetry. The implanted device is capable of transmitting event markers to the external device, the event markers reflecting the occurrence of identified physiologic and device-initiated events. The external device includes circuitry for generating an interactive diagram illustrating the interrelation between marker events, and a display screen for presenting a graphical image of the marker diagram to the user. In addition, the external device defines a plurality of 'hot spots' in the area of the diagram, such that when a user selects a particular area of the diagram on the display, using, for example, a mouse or other cursor control device, a context-sensitive explanatory message is displayed to the user. In the disclosed embodiment, expert system software is executed by a computer subsystem of the external device. The expert system software is supplied with a knowledge base specific to a particular model of implanted device, the knowledge base providing the expert system with the rules necessary for proper interpretation and explanation of the event marker diagram.
