Abstract: An external programming system and method for implantable medical devices (IMDs) is disclosed. The external programming system includes a communication circuit, a display device, an input device, and a processor. The communication circuit is configured to link to an IMD to transmit or monitor IMD timing parameter settings. The display device is configured to display a textual representation of an IMD timing parameter setting and a specified IMD timing parameter limit, a graphical slide control comprising a movable feature indicating the IMD timing parameter setting, a graphical slide-control limit corresponding to the specified IMD timing parameter limit, and a graphical representation of physiologic information including a portion of said graphical representation aligned with the slide control movable feature. The input device is configured to adjust the movable feature in response to user input. The processor is configured to monitor or store an IMD timing parameter setting.

Abstract: A medical device programmer automatically adjusts parameters to be programmed to a medical device in response to a user modifying related parameters. Slide controllers on the programmer display screen can adjust parameters. In response to slide controller movement, the programmer automatically adjusts related parameters by moving their slide controllers. This graphically illustrates to the user the automatic adjustments being made to the related parameters. and the relationship between parameters being adjusted by the user and automatically. In response to on screen parameter changes, the system graphically illustrates the parameter values that are changed and those that are programmed to the medical device and those that would cause unsafe condition in the medical device if programmed. The method also prevents the programming to the medical device the parameters that would cause an unsafe condition.
