Detecting worsening heart failure
First Claim
1. A method comprising:
- monitoring a heart rate, a respiration rate and an activity level of a patient;
comparing the monitored heart rate, respiration rate and activity level to a predetermined threshold zone which is a function of heart rate, respiration rate and activity level;
determining the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone; and
after determining the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone, issuing an alert to indicate that the patient is experiencing worsening heart failure.

10. A medical system for monitoring a condition of a patient comprising:
-
one or more sensors configured to output one or more signals indicative of a heart rate, a respiration rate and an activity level of the patient; a memory configured to store an indication of a predetermined threshold zone which is a function of heart rate, respiration rate and activity level; a diagnostic unit configured to; compare the monitored heart rate, respiration rate and activity level to the predetermined threshold zone, and determine the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone; and an alert module configured to issue an alert to indicate that the patient is experiencing worsening heart failure after the diagnostic unit determines the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A system comprising:
-
means for monitoring a heart rate of a patient; means for monitoring a respiration rate of the patient; means for monitoring an activity level of the patient; means for comparing the monitored heart rate, respiration rate and activity level to a predetermined threshold zone which is a function of heart rate, respiration rate and activity level; means for determining the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone; and means for, after determining the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone, issuing an alert to indicate that the patient is experiencing worsening heart failure.

20. A non-transitory computer readable storage medium comprising instructions that cause a processor to:
-
monitor a heart rate, a respiration rate and an activity level of a patient; compare the monitored heart rate, respiration rate and activity level to a predetermined threshold zone which is a function of heart rate, respiration rate and activity level; determine the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone; and after determining the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone, issue an alert to indicate that the patient is experiencing worsening heart failure.
