An implantable medical device determines activity levels over a set of time periods, preferably on the order of seconds, minutes and hours and a display is enabled for days or weeks at recorded activity levels over a range of dates. This enables physical review of patient functional status. Additional physiologic data can be recorded along with the activity data, and this too may be reported out from the implanted device to a medical communications system for alarm purposes, filtrating drugs or other monitoring tasks.

[ What is claimed is:] [1.]1. A method of tracking patient functional status including the methods of:a.) measuring activity counts with an implantable activity sensor;b.) determining a number of activity counts sensed during a first time period of a first predetermined length, and if the number of sensed activity counts is greater than a predetermined value, recording the time period as an activity period;c.) repeating for a predetermined number of subsequent time periods of the first predetermined length; andd.) titrating patient medication levels based on a patient's activity level as indicated by the number of time periods of the first predetermined length that are designated as activity periods.
