Patient activity and heart rate (HR) are monitored. For each of a plurality of time periods, periods of patient exercise and/or patient activity, if any, are detected based on the monitored patient activity and HR and an activity threshold. A cumulative duration of exercise and/or a cumulative duration of activity is/are determined for each time period, and the peak exercise HR for each period of patient exercise is detected. Information is stored, including duration information indicative of the cumulative duration of exercise and/or the cumulative duration of activity for each time period, and peak exercise information associated with the period of patient exercise during which the highest peak exercise HR occurred for each time period. The stored duration information, or information indicative thereof, are transferred from an implantable system to a non-implanted system so that a graphical representation of such information can be displayed and observed to evaluate exercise compliance and/or heart failure condition. |
