Claim One:
1. A medical device system, comprising: an implantable device including a pulse generator having means for generating stimulating pulses and sensor circuitry means for detecting physiological events; implantable device control circuitry coupled to said pulse generator and to said sensing circuitry, said control circuitry operative to trigger said pulse generator to deliver said stimulating pulses in response to physiological events; a transmitter circuit coupled to said implantable device control circuitry further comprising telemetry circuitry responsive to delivery of said stimulating pulses and detection of said physiological events by said sensor circuitry means for transmitting event marker signals; an external unit having a graphics display screen, said external unit further comprising: a receiver circuit means for receiving said event marker signals and means for displaying sequences of said event marker signals on said graphics display screen; means for storing a knowledge base comprising information concerning operational characteristics of said implantable device; a user input device having means for enabling a user to select a point within a displayed sequence of said event marker signals on said graphics display screen; means responsive to selection of a point within a displayed sequence of event marker signals for applying the information in said knowledge base to the sequence of event marker Signals to generate an explanatory message explaining operation of said implantable device at said selected point; and means for displaying said explanatory message on said graphics display screen.
