1. A method comprising:
- configuring a medical data management device to collect values of one or more physiological parameters along with associated timestamps indicative of the times at which the parameter values were measured;
configuring an implantable medical device that includes circuitry for measuring values of one or more physiological parameters to communicate the parameter values to the medical data management device along with associated timestamps indicative of the times at which the parameter values were measured; and
,configuring the medical data management device to use the timestamps associated with the collected parameter values of a physiological parameter to measure the periodic variation, if any, of that particular physiological parameter, and wherein the periodic variation of a physiological parameter is determined by computing an autocorrelation function of a time series of collected parameter values.

Abstract
A patient management system is described that includes an implantable device for collecting one or more physiological parameter values and associated timestamps indicating the time at which the value is collected. The system is then configured to determine the periodic variation, if any, of a particular physiological parameter and use that periodicity in assessing changes in the parameter values over time.
