Abstract

Heart rhythm status information can be provided to a user, including providing a normal heart rhythm indication if detected electrocardiogram data is indicative of a normal heart rhythm, providing an abnormal heart rhythm indication if detected electrocardiogram data is indicative of an abnormal heart rhythm. Further, a current heart rhythm can be recorded, including recording the current heart rhythm in response to the provided abnormal heart rhythm indication if an abnormal heart rhythm indication is provided in response to the first query command, and recording the current heart rhythm in response to a second patient-initiated query command from the user-interface device following a normal heart rhythm indication in response to the first query command.

Claims

1. A system comprising:

an implantable cardiac rhythm management device configured to detect electrocardiogram data of a patient'"'"'s heart and to provide a cardiac rhythm therapy to a patient;

a handheld patient-operated user-interface device, communicatively coupled to the cardiac rhythm management device, the user-interface device configured to deliver a first patient-initiated query command to the cardiac rhythm management device, to receive heart rhythm status information from the cardiac rhythm management device, and to provide the heart rhythm status information to the patient in response to the first query command, the heart rhythm status information including;

a normal rhythm indication if the heart rhythm status information is indicative of a normal heart rhythm;

an abnormal rhythm indication if the heart rhythm status information is indicative of an abnormal heart rhythm; and

wherein the cardiac rhythm management device is configured to record a current heart rhythm in response to the provided abnormal rhythm indication if the abnormal rhythm indication is provided in response to the first query command; and

wherein the cardiac rhythm management device is configured to record a current heart rhythm in response to a second patient-initiated query command delivered to the cardiac rhythm management device following the provided normal rhythm indication in response to the first query.

2. The system of claim 1, wherein the user-interface device includes a plurality of physically separated deadfront status indicators configured to provide the heart rhythm status information to the patient, the plurality of deadfront status indicators differentiated from each other by the use of different pictorial graphic shapes that convey information pictographically.

3. The system of claim 2, wherein the plurality of deadfront status indicators includes:

a normal rhythm indicative deadfront status indicator; and

an abnormal rhythm indicative deadfront status indictor.

4. The system of claim 3, wherein the normal rhythm indicative deadfront status indicator includes a green colored icon in a heart shape, and wherein the abnormal rhythm indicative deadfront status indictor includes a yellow colored icon in the shape of a heart with a sharp jagged line extending across the heart.

5. The system of claim 1, wherein the user-interface device is configured to provide cardiac rhythm management device status information to the patient in response to the first query command, wherein the cardiac rhythm management device status information includes an indication of the current status of the cardiac rhythm management device;

and

wherein the user-interface device is configured to provide heart rhythm status information if a therapy has not been scheduled by the cardiac rhythm management device.

6. The system of claim 5, wherein the user-interface device is configured to provide the indication of the current status of the cardiac rhythm management device using a therapy pending indicative deadfront status indicator.

8. The system of claim 1, wherein the heart rhythm status information includes a contact caregiver indication if the heart rhythm status information is indicative of a condition requiring physician intervention.

9. The system of claim 8, wherein the cardiac rhythm management device is configured to record a current heart rhythm in response to the provided contact caregiver indication if the contact caregiver indication is provided in response to the first query command.

10. The system of claim 9, wherein the user-interface device includes a contact caregiver indicative deadfront status indicator configured to provide the heart rhythm status information to the patient, the contact caregiver indicative deadfront status indicator including a red colored icon in the shape of a telephone having a base unit with a cross in the center of the base unit.

7. The system of claim 7, wherein the therapy pending indicative deadfront status indicator includes an orange colored icon in a heart shape with a clock face positioned in the heart shape.

11. A method comprising:

querying an implantable cardiac rhythm management device using a first patient-initiated query command from a handheld patient-operated user-interface device;

providing heart rhythm status information to the user-interface device from the cardiac rhythm management device in response to the first query command, the heart rhythm status information indicating a status of a patient'"'"'s heart rhythm using electrocardiogram data detected by the cardiac rhythm management device, the providing the heart rhythm status information including;

providing a normal heart rhythm indication if the detected electrocardiogram data is indicative of a normal heart rhythm;

providing an abnormal heart rhythm indication if the detected electrocardiogram data is indicative of an abnormal heart rhythm; and

recording a current heart rhythm using the cardiac rhythm management device, the recording the current heart rhythm including;

recording the current heart rhythm in response to the provided abnormal heart rhythm indication if an abnormal heart rhythm indication is provided in response to the first query command; and

recording the current heart rhythm in response to a second patient-initiated query command from the user-interface device following a normal heart rhythm indication in response to the first query command.

12. The method of claim 11, wherein the providing the heart rhythm status information includes using a plurality of physically separated deadfront status indicators, the plurality of deadfront status indicators differentiated from each other by the use of different pictorial graphic shapes that convey information pictographically.

13. The method of claim 12, wherein the providing the normal heart rhythm indication includes using a normal rhythm indicative deadfront status indicator, and wherein the providing the abnormal heart rhythm indication includes using an abnormal rhythm indicative deadfront status indictor.

14. The method of claim 13, wherein the using the normal rhythm indicative deadfront status indicator includes using a green colored icon in a heart shape, and wherein the using the abnormal rhythm indicative deadfront status indictor includes using a yellow colored icon in the shape of a heart with a sharp jagged line extending across the heart.

15. The method of claim 11, including:

providing cardiac rhythm management device status information to the user-interface device from the cardiac rhythm management device in response to the first query command, wherein the cardiac rhythm management device status information includes an indication of the current status of the cardiac rhythm management device; and

wherein the providing the heart rhythm status information includes providing heart rhythm status information if a therapy has not been scheduled by the cardiac rhythm management device.

16. The method of claim 11, wherein the providing the heart rhythm status information includes providing a contact caregiver indication if the detected electrocardiogram data is indicative of a condition requiring intervention of a physician.

17. The system of claim 16, wherein the recording the current heart rhythm includes recording the current heart rhythm in response to the provided contact caregiver indication if the contact caregiver indication is provided in response to the first query command.

18. The method of claim 16, wherein the providing the contact caregiver indication includes using a contact caregiver indicative deadfront status indicator, the contact caregiver indicative deadfront status indicator including a red colored icon in the shape of a telephone having a base unit with a cross in the center of the base unit.
