Improved graphic interface for pacemaker programmers

A graphic user interface (P) for a cardiac implant, such as an implant programmer (38), includes image generators (24, 26) for generating multiple images on a screen (16), each image corresponding to as representation of a parameter related to the operation of the implant (38) or a cardiac function, and an indicia generator (27) for superimposing on the images an indicia indicative of the interrelation between the parameters. The indicia allows a user to obtain a clear understanding and appreciation of the cause and effect rules between various cardiac parameters and/or functions, the parameters or functions could be actual, i.e., obtained from the implant (38) and/or the patient's heart, or they can be simulated to provide the user an indication on how the pacemaker will operate under these simulated conditions parameters.
