Abstract

Embodiments of the invention are related to medical systems and methods that can be used to control features of implanted medical devices, amongst other things. In an embodiment, the invention includes a medical system including an external medical device. The external medical device including a video output and a processor in communication with the video output. The system can be configured to display information through the video output as a graph, the graph comprising data representing pacing rates of an implantable device as a function of activity level over time. The system can further be configured to accept user input through direct manipulation of the graph. Other embodiments are also included herein.
