Abstract

A wearable treatment device includes a cardiac sensing electrode, a treatment electrode, a user interface, and a sensor. The cardiac sensing electrode detects cardiac information, and the treatment electrode applies treatment to a subject. The user interface receives quality of life information from the subject, and the sensor detects subject activity and wellness information. A controller coupled with the cardiac sensing electrode, the treatment electrode, the user interface, and the sensor receives the detected cardiac information, the quality of life information, and the detected subject activity and wellness information, and determines that treatment is to be applied to the body of the subject based upon the detected cardiac information. The controller can adjust the treatment based on at least one of the detected subject activity and wellness information and the quality of life information.

Claims

1. A wearable treatment device for treatment of a subject, comprising:

a plurality of cardiac sensing electrodes configured to be positioned outside a body of the subject and to detect cardiac information of the subject;

at least one treatment electrode configured to be positioned outside the body of the subject and to apply treatment to the subject;

at least one activity sensor configured to be positioned outside the body of the subject and to detect subject activity information;

a monitor having a user interface configured to guide the subject through a predetermined test; and

a controller communicatively coupled to the plurality of cardiac sensing electrodes, the at least one treatment electrode, the monitor, and the at least one activity sensor, the controller configured to receive and record the detected cardiac information and the detected subject activity information during the predetermined test, to determine whether treatment should be applied to the body of the subject based upon the detected cardiac information, and to initiate the treatment of the subject in response to a determination that the treatment should be applied to the body of the subject during the predetermined test.

2. The wearable treatment device of claim 1, wherein the controller is further configured to receive and record the detected cardiac information and the detected subject activity information before and after the predetermined test.

3. The wearable treatment device of claim 2, wherein the controller is further configured to determine whether treatment should be applied to the body of the subject based upon the detected cardiac information before and after the predetermined test, and to initiate the treatment of the subject in response to a determination that the treatment should be applied to the body of the subject before and after the predetermined test.

4. The wearable treatment device of claim 3, wherein the predetermined test is a six minute walk test.

5. The wearable treatment device of claim 4, wherein the at least one activity sensor includes at least one accelerometer.

6. The wearable treatment device of claim 5, wherein the at least one activity sensor further includes a pedometer.

7. The wearable treatment device of claim 5, further comprising at least one additional sensor communicatively coupled to the controller to detect at least one of blood pressure, blood oxygen level, respiration, and temperature.

8. The wearable treatment device of claim 7, wherein the user interface is further configured to receive quality of life information from the subject, and wherein the controller is further configured to adjust the treatment based on the detected cardiac information and at least one of the detected activity information and the quality of life information.

9. The wearable treatment device of claim 8, wherein the quality of life information includes information about at least one of the subject'"'"'s lifestyle, body weight, blood pressure, eating and exercise habits, and how the subject currently feels.

10. The wearable treatment device of claim 1, wherein the predetermined test is a six minute walk test, and wherein the at least one activity sensor includes at least one accelerometer.

11. The wearable treatment device of claim 10, further comprising at least one additional sensor communicatively coupled to the controller to detect at least one of blood pressure, blood oxygen level, respiration, and temperature.

12. The wearable treatment device of claim 11, wherein the user interface is further configured to receive quality of life information from the subject, the quality of life information including information about at least one of the subject'"'"'s lifestyle, body weight, blood pressure, eating and exercise habits, and how the subject currently feels.

13. A method of facilitating care of a subject, comprising:

guiding the subject through a predetermined test;

sensing cardiac information of the subject and subject activity information of the subject during the predetermined test;

recording the sensed cardiac information and the sensed subject activity information during the predetermined test;

determining, during the predetermined test, whether treatment should be applied to a body of the subject based upon the sensed cardiac information; and

applying the treatment to the body of the subject in response to a determination that the treatment should be applied to the body of the subject during the predetermined test.

14. The method of claim 13, further comprising:

sensing the cardiac information of the subject and the subject activity information of the subject before and after the predetermined test; and

recording the sensed cardiac information and the sensed subject activity information before and after the predetermined test.

15. The method of claim 14, further comprising:

determining, before and after the predetermined test, whether treatment should be applied to the body of the subject based upon the sensed cardiac information before and after the predetermined test; and

applying the treatment to the body of the subject in response to a determination that the treatment should be applied to the body of the subject before and after the predetermined test.

16. The method of claim 14, wherein guiding the subject through a predetermined test includes guiding the subject through a six minute walk test.

17. The method of claim 16, further comprising:

sensing at least one of the subject'"'"'s blood pressure, blood oxygen level, respiration, and temperature before, during, and after the predetermined test; and

recording the at least one of the subject'"'"'s blood pressure, blood oxygen level, respiration, and temperature before, during, and after the predetermined test.

18. The method of claim 17, further comprising:

receiving quality of life information from the subject; and

adjusting the treatment to be applied to the body of the subject based upon the sensed cardiac information and at least one of the sensed subject activity information and the quality of life information.

19. The method of claim 18, wherein receiving quality of life information from the subject includes receiving quality of life information from the subject indicative of at least one of the subject'"'"'s lifestyle, body weight, blood pressure, eating and exercise habits, and how the subject currently feels.

20. The method of claim 15, further comprising:

sensing at least one of the subject'"'"'s blood pressure, blood oxygen level, respiration, and temperature before, during, and after the predetermined test; and

recording the at least one of the subject'"'"'s blood pressure, blood oxygen level, respiration, and temperature before, during, and after the predetermined test.
