Abstract
A method of presenting information for evaluating the condition of chronically impaired cardiac patients based on long-term assessment of activity trends, using a memoried implanted cardiac rhythm management device having a plurality of programmable parameters and one or more sensors for sensing one or more parameters related to an activity level of the patient. The method includes acquiring sensor signal data indicative of the activity level of the patient, accumulating sensor signal data in memory and using the accumulated sensor signal data to determine the activity level of the patient during a predetermined period of time, recording the activity level during a plurality of sequential time periods, adding contemporary annotation information to the activity data and producing a data record of the activity level with the annotation information during sequential time periods sufficient to indicate trends in a patient's activity level.
