Abstract

According to another example, a wearable medical device controller is provided. The device controller includes a memory and a processor coupled to the memory. The processor is configured to determine a correlation between a phenomenon identifiable by the wearable medical device controller and at least one response pattern associated with a patient and store, responsive to detecting the correlation, an adaptation path to address the at least one response pattern, the adaptation path specifying an adaptation of at least one characteristic of an alarm. The at least one response pattern may include a plurality of response patterns and the adaptation path may reflect adaptations made to address at least some of the plurality of response patterns.

Claims

1. A system comprising:

an ambulatory medical device comprising

at least one sensor configured to acquire electrocardiogram (ECG) signals from a patient;

a network interface configured to communicate wirelessly with an electronic device distinct from the ambulatory medical device;

a user interface;

a memory storing alarm information specifying one or more alarms and one or more conduits through which the one or more alarms are to be provided; and

at least one processor coupled to the memory, the network interface, the user interface, and the at least one sensor and configured to

monitor ECG data based on the ECG signals to detect a cardiac abnormality in the patient

identify, based on the alarm information, an alarm of the one or more alarms triggered by the cardiac abnormality;

adapt, based on the alarm information, the alarm to output via at least one conduit of the one or more conduits, the one or more conduits comprising

the network interface configured to communicate wirelessly with the electronic device, and

the user interface of the ambulatory medical device; and

the electronic device, the electronic device being configured to receive the alarm; and

issue the alarm.

2. The system of claim 1, wherein the electronic device comprises one or more of an earpiece, a smart phone, a tablet computing device, an article of clothing, and in-vehicle entertainment system, and a home security system.

3. The system of claim 1, wherein the ambulatory medical device further comprises a therapy delivery interface coupled to the at least one processor and the at least one processor is further configured to adapt, based on the alarm information, the alarm to issue via the therapy delivery interface.

4. The system of claim 1, wherein to adapt the alarm comprises to change the at least one conduit to comprise the network interface, the user interface, or both the network interface and the user interface.

5. The system of claim 4, wherein to change the one or more conduits comprises to transmit the alarm to the electronic device via the network interface.

6. The system of claim 5, wherein the electronic device comprises an earpiece and to issue the alarm comprises to issue an alarm via the earpiece.

7. The system of claim 5, wherein the electronic device comprises an article of clothing and to issue the alarm comprises to issue an alarm via the article of clothing.

8. The system of claim 5, wherein the electronic device comprises an in-vehicle entertainment system and to issue the alarm comprises to issue an alarm via the in-vehicle entertainment system.

9. The system of claim 5, wherein the electronic device comprises a personal electronic device and to issue the alarm comprises to issue an alarm via the personal electronic device.

10. The system of claim 9, wherein the personal electronic device comprises a smart phone and to issue the alarm via the personal electronic device comprises to issue an alarm via the smart phone.

11. The system of claim 9, wherein the the personal electronic device comprises a smart phone and to issue the alarm via the personal electronic device comprises to place a phone call or send a text message.

12. The system of claim 9, wherein to issue the alarm via the personal electronic device comprises to preempt normal functioning of the personal electronic device.

13. The system of claim 9, wherein the personal electronic device comprises a smart phone and to preempt normal functioning of the personal electronic device comprises to send an alarm via an active phone call.

14. The system of claim 9, wherein the the personal electronic device comprises a tablet computing device and to issue the alarm via the personal electronic device to issue an alarm via the tablet computing device.

15. The system of claim 5, wherein the electronic device comprises a display and to issue the alarm comprises to issue an alarm via the display.

16. The system of claim 5, wherein the electronic device comprises a home security system and to issue the alarm comprises to issue an alarm via the home security system.

17. The system of claim 5, wherein the at least one sensor is coupled to a light emitting diode and the at least one processor is configured to issue the alarm via the light emitting diode.

18. A method of adapting alarms in an ambulatory medical device, comprising:

storing, in a memory of the ambulatory medical device, alarm information specifying one or more alarms and one or more conduits through which the one or more alarms are to be provided;

acquiring electrocardiogram (ECG) signals from a patient coupled to the ambulatory medical device;

monitoring ECG data based on the ECG signals to detect a cardiac abnormality in the patient;

identifying, based on the alarm information stored in the memory of the ambulatory medical device, an alarm of the one or more alarms triggered by the cardiac abnormality;

adapting, based on the alarm information stored in the memory of the ambulatory medical device, the alarm to output via at least one conduit of the one or more conduits, the one or more conduits comprising a network interface configured to communicate wirelessly with an electronic device and a user interface of the ambulatory medical device;

receiving the alarm at the electronic device via the network interface of the ambulatory medical device; and

issuing the alarm via the electronic device.

19. The method of claim 18, wherein adapting the alarm comprises selecting the at least one conduit to output the alarm to be at least one of the network interface, the user interface, or both the network interface and the user interface.

20. The method of claim 18, wherein the electronic device comprises a smart phone and issuing the alarm comprises issuing an alarm via the smart phone.
