A graphic user interface for a cardiac implant, such as an implant programmer, includes image generators for generating multiple images on a screen, each image corresponding to as representation of a parameter related to the operation of the implant or a cardiac function, and an indicia generator 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 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.

A diagnostic device for providing a prognosis of patient with an implanted cardiac device includes a data bank for storing statistical data relating various symptoms characterizing cardiac problems and associated complications. The device further includes an input device so that a clinician can enter patient specific data including his symptoms. A set of rules stored in a memory are used to provide a diagnosis for the patient based on the statistical data. Preferably the diagnostic device is incorporated in a programmer for a pacemaker or other implantable cardiac device.
