1. A method for tracking quality of life in a patient with angina, said method comprising:
- obtaining activity data and cardiac data over multiple sample intervals within a trending period of time;
determining, based on the activity data for each of the sample intervals, whether a level of physical activity of the patient reaches a predetermined state;
identifying an ischemic episodes based on the cardiac data for the corresponding sample intervals in which the level of the physical activity reaches the predetermined state;
recording an activity level associated with each of the ischemic episodes; and
presenting trend information indicating the activity levels and a number of the ischemic episodes over the trending period of time, wherein the trend information includes a graph that plots the activity levels and number of ischemic episodes along first and second axes and time along a third axis.

Abstract
A method and system for tracking quality of life in a patient with angina includes obtaining activity data and cardiac data, determining a level of physical activity of the patient and identifying an ischemic episode based on the cardiac data obtained during the physical activity. The method also provides for recording an activity level at the time the ischemic episode occurs. Furthermore, the method also provides for presenting activity level trends related to activity levels at the onset of ischemia to a user.

8. A method comprising:
-
monitoring for an ischemic event during a time when an activity level of a patient satisfies a predetermined condition; if an ischemic event is detected, recording activity data associated with the detected ischemic event; and performing the monitoring and recording operations over multiple sample intervals within a trending period of time and presenting trend information indicating the recorded activity data and a number of the ischemic episodes over the trending period of time, wherein the trend information includes a graph that plots the activity levels and number of ischemic episodes along first and second axes and time along a third axis. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
