First Claim
Patent Images
1. A method for tracking quality of life in a patient with angina, said method comprising:
- obtaining activity data and cardiac data;
determining, based on the activity data, when a level of physical activity of the patient reaches a predetermined state;
identifying an ischemic episode based on the cardiac data obtained during the physical activity;
recording an activity level associated with the ischemic episode; and
presenting trend information related to the activity levels.

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.

13. A system for tracking quality of life in a patient with angina, said system comprising:
-
memory storing cardiac signals representative of cardiac activity having ST segment variation and storing activity data for an exercising patient over a period of time; and a processor configured to; (i) determine, based on the activity data, when a level of physical activity of the patient reaches a predetermined state; (ii) identify an ischemic episode based on the cardiac data obtained during the physical activity; and (iii) record the activity level associated with the ischemic episode; and
an output to preset trend information related to the activity levels. - View Dependent Claims (14, 15, 16, 18, 22, 23)
