Abstract

A patient diagnostic emergency room triage system includes an implanted cardiac device which may be a cardiosaver, pacemaker or cardiac defibrillator for recording electrogram data associated with the detection of a cardiac event. A communication mechanism receives electrogram data from the implanted cardiac device and a visual display displays the electrogram data recorded by the implanted cardiac device. The visual display permits displaying electrogram data associated with an ST segment related cardiac event.

Claims

1. A system for diagnosis of a patient having an implanted cardiac device, the system including:

an implanted cardiac device including means for detecting a cardiac event, means for alerting the patient that the cardiac event has occurred, means for storing electrogram data associated with the cardiac event, and communication means for wirelessly transmitting the electrogram data from the implanted cardiac device to an emergency room triage system, wherein

the emergency room triage system includes communication means to wirelessly receive electrogram data from the implanted cardiac device and means for displaying the electrogram data associated with the cardiac event where the patient has been alerted.

2. The system of claim 1, wherein said implanted cardiac device includes pacemaker circuitry.

3. The system of claim 1, wherein said implanted cardiac device includes cardiac defibrillator circuitry.

4. The system of claim 1, wherein the cardiac event is a heart attack.

5. The system of claim 1, wherein the cardiac event is a detected heart arrhythmia.

6. The system of claim 1 wherein the cardiac device includes means to store regular electrogram data that is not associated with any cardiac event and the emergency room triage system includes means to display the regular electrogram data.

7. The system of claim 1, further including means for displaying ongoing electrogram data transmitted in real time from the implanted cardiac device.

8. The system of claim 1, wherein the means for displaying electrogram data includes a computer display screen.

9. The system of claim 1, wherein the means for displaying electrogram data includes a printer.

10. The system of claim 1 wherein the range of the communication means is greater than 1 foot.

11. The system of claim 1 wherein the emergency room triage system includes means to display the type of cardiac event associated with the displayed electrogram data.

12. The system of claim 1, wherein said implanted cardiac device has at least two levels of patient alerting, at least one of the at least two levels being an emergency alarm which indicates that the patient should seek immediate medical attention.

13. The system of claim 12, wherein the cardiac device will first transmit electrogram data associated with the emergency alarm before it transmits any other electrogram data to the emergency room triage system.

14. The system of claim 1 wherein the implanted cardiac device means for alerting the patient includes internal alarm means that produces an internal alarm signal from the implanted device to notify the patient when the implanted device detects the cardiac event.

15. The system of claim 14, wherein the internal alarm signal is a vibration.

16. The system of claim 14, wherein the internal alarm signal is a sound.

17. The system of claim 14, wherein the internal alarm signal is an electrical tickle.

18. The system of claim 14 wherein the implanted cardiac device means for alerting the patient includes external alarm means that produces an external alarm signal from the implanted device to notify the patient when the implanted device detects the cardiac event.

19. The system of claim 18, wherein the external alarm signal is a sound.

20. The system of claim 18, wherein the external alarm signal is a visual display.

21. The system of claim 1 wherein the implanted cardiac device means for alerting the patient includes external alarm means that produces an external alarm signal from the implanted device to notify the patient when the implanted device detects the cardiac event.

22. The system of claim 21, wherein the external alarm signal is a sound.

23. The system of claim 21, wherein the external alarm signal is a visual display.

24. The system of claim 1, wherein the communication means for transmitting the electrogram data from the implanted cardiac device is configured to transmit over the Federal Communications Commission Medical Implant Communications Service band.

25. A method for diagnosing a cardiac event in a human patient, the method comprising the steps of:

a. implanting a cardiosaver, the cardiosaver including the capabilities to detect at least one type of cardiac event, the cardiosaver also including means to alert the patient when the at least one type of cardiac event is detected;

b. installing an emergency room triage system in at least one medical center, the emergency room triage system including means to receive electrogram data wirelessly transmitted from the cardiosaver after the patient arrives at the medical center;

c. training medical practitioners at the medical center having the installed emergency room triage system as to the operation of the emergency room triage system so that the medical practitioners can view the electrogram data from the cardiosaver and provide appropriate medical treatment for the cardiac event that triggered the patient alert.

26. The method of claim 25 where the medical center is located within one hour'"'"'s driving time from the patient'"'"'s home.

27. The method of claim 25 where the medical center is located within one hour'"'"'s driving time of the patient'"'"'s place of work.

28. The method of claim 25 where the emergency room triage system is installed in at least one medical center in a major metropolitan area.

29. An emergency room triage system for diagnosis of a patient having an implanted cardiac device, the system including:

means for receiving an alert from the implanted cardiac device, the alert indicating that a cardiac event has occurred, first communication means for receiving electrogram data from the implanted cardiac device, the electrogram data being associated with the cardiac event;

means for displaying said electrogram data, and second communication means for sending instructions to the patient.

30. The system of claim 29, wherein said implanted cardiac device includes pacemaker circuitry.

31. The system of claim 29, wherein said implanted cardiac device includes cardiac defibrillator circuitry

32. The system of claim 29, wherein the cardiac event is a heart attack.

33. The system of claim 29 wherein the cardiac event is an ST segment shift t.

34. The system of claim 29, wherein the cardiac event is an arrhythmia.

35. The system of claim 29 wherein the cardiac device includes third communication means for receiving instructions from the second communication means for sending instructions to the patient.

36. The system of claim 29, wherein the means for displaying electrogram data comprise a computer display screen.

37. The system of claim 29, wherein the means for displaying electrogram data comprise a printer.
