Abstract

Technologies and implementations for a wearable healthcare system including a remote device, a server, and a configurable comparator module (CCM). The CCM may be configured to facilitate communication between the server and a remote device. A wearable medical device (WMD) may be configured to provide electrocardiogram (ECG) data to the server. The CCM may be configured capture one or more portions of the ECG data to be configured and compared at the remote device. Accordingly, the CCM may be configured to display the one or more portions at the remote device capable of being utilized by a person at the remote device.

Claims (36)

1. A wearable medical device (WMD) system, comprising:

a remote device;

a wearable medical device (WMD), the WMD configured to communicate electrocardiogram (ECG) data to the remote device; and

a configurable comparator module (CCM), the CCM configured to:

capture a first portion of the ECG data based on a predetermined parameter, the first portion of the ECG data indicative of a non-episode portion of the ECG data,

capture a second portion of the ECG data, the second portion of the ECG data indicative of an episode portion of the ECG data,

cause to display at least the first portion and the second portion of the ECG data concurrently,

facilitate selection of a portion among the displayed first portion and the displayed second portion of the ECG data, and

automatically identify a type of rhythm corresponding to the selected portion of the ECG data for comparison by a user for use in a medical diagnosis.

2. The WMD system of claim 1 , wherein the CCM is hosted on the remote device.

3. The WMD system of claim 1 , wherein the predetermined parameter comprises a user selectable parameter.

4. The WMD system of claim 1 , wherein the CCM is further configured to capture a third portion of the ECG data and cause to display the third portion of the ECG data concurrently with the first portion and the second portion of the ECG data, and wherein an R-wave peak of the third portion of the ECG data is aligned with R-wave peaks of the first portion and the second portion of the ECG data.

5. The WMD system of claim 4 , wherein the third portion of the ECG data comprises a user selectable portion.

6. The WMD system of claim 1 , wherein the predetermined parameter comprises an event detected by the WMD.

7. The WMD system of claim 6 , wherein the second portion of the ECG data comprises a preceding portion of the ECG data, and wherein the preceding portion is captured a predetermined amount of time preceding the detected event.

8. The WMD system of claim 1 , wherein the WMD comprises a wearable cardioverter defibrillator (WCD).

9. The WMD system of claim 1 , wherein the predetermined parameter comprises a periodic trigger.

10. The WMD system of claim 1 , wherein the second portion of the ECG data comprises a baseline portion of the ECG data, the baseline portion of the ECG data being a baseline portion captured during a non-episodic normal sinus rhythm.

11. The WMD system of claim 10 , wherein the baseline portion of the ECG data comprises the non-episodic normal sinus rhythm captured during an exercising heart rate.

12. The WMD system of claim 10 , wherein the baseline portion of the ECG data comprises the non-episodic normal sinus rhythm captured during a sleeping heart rate.

13. The WMD system of claim 10 , wherein the baseline portion of the ECG data comprises the non-episodic normal sinus rhythm captured during a sitting heart rate.

14. The WMD system of claim 1 , wherein the CCM is configured to cause to display the first portion and the second portion of the ECG data overlayed on top of each other.

15. The WMD system of claim 14 , wherein the first portion and the second portion of the ECG data comprises user interactable first portion and second portion.

16. The WMD system of claim 1 , wherein the CCM is configured to cause to display so that an R-wave peak of the first portion of the ECG data is aligned with an R-wave peak of the second portion of the ECG data.

17. The WMD system of claim 1 , wherein to capture the first portion of the ECG data, the CCM is configured to determine whether the first portion is the non-episode portion of the ECG data, and wherein to capture the second portion of the ECG data, the CCM is configured to determine whether the second portion is the episode portion of the ECG data.

18. A wearable medical device (WMD) system, comprising:

a remote device;

a WMD configured to communicate electrocardiogram (ECG) data to the remote device;

means for capturing a first portion and a second portion of the ECG data, the first portion being indicative of a non-episode portion of the ECG data and the second portion being indicative of an episode portion of the ECG data,

means for displaying at least the first portion and the second portion of the ECG data concurrently,

means for facilitating selection of a portion among the displayed first portion and the displayed second portion of the ECG data, and

means for automatically identifying a type of rhythm corresponding to the selected portion of the ECG data for comparison by a user for use in a medical diagnosis.

19. The WMD system of claim 18 , wherein the means for capturing and the means for displaying are hosted on the remote device.

20. The WMD system of claim 18 , wherein the second portion of the ECG data comprises a baseline portion of the ECG data, the baseline portion being a baseline portion during a non-episodic normal sinus rhythm.

21. The WMD system of claim 18 , wherein the means for displaying comprises a means for displaying the first portion and the second portion of the ECG data overlayed on top of each other.

22. The WMD system of claim 18 , wherein the means for displaying comprises means for displaying the first portion and the second portion of the ECG data concurrently so that an R-wave peak of the first portion of the ECG data is aligned with an R-wave peak of the second portion of the ECG data.
