Methods and systems for detecting medical disorders through synergistic use of one or more medical devices are described. One or more medical devices are selected to sense one or more physiological parameters associated with a medical disorder. A presence of the medical disorder is assessed based on the sensed parameters. The medical devices used for sensing may be selected from a plurality of patient internal and/or patient-external medical devices.
