Abstract:
An implantable medical device monitoring method, the method comprising the steps of:providing at least one sensor output signal to an implantable medical device;providing chronic data representative of at least one physiological parameter based on the at least one sensor output signal;establishing a baseline representative of an initial state of the at least one physiological parameter using chronic data provided in an initial sample time period;monitoring the chronic data to detect a change in state of the at least one physiological parameter relative to the baseline;storing data associated with a detected change in state of the at least one physiological parameter within the implantable medical device;reestablishing the baseline for the at least one physiological parameter if a change in state is detected, wherein the baseline is reestablished using chronic data available upon or after detection of the change of state; andrepeating the monitoring, storing, and reestablishing steps.
