Abstract

Embodiments of the present invention provide a method of analyzing cardiac information by collecting a plurality of self-contained, wearable, portable cardiac monitors each of the cardiac monitors electronically storing at least 24 hours of continuously detected and unanalyzed cardiac signals from a mammal. Next, retrieving cardiac information stored in each of the plurality of self-contained portable cardiac monitors. Next, forwarding retrieved cardiac information.

Claims

1. A method of analyzing cardiac information, comprising:

Collecting a plurality of self-contained, wearable, portable cardiac monitors each of the cardiac monitors electronically storing at least 24 hours of continuously detected and unanalyzed cardiac signals from a mammal;

Retrieving cardiac information stored in each of the plurality of self-contained portable cardiac monitors; and

Forwarding retrieved cardiac information.

2. The method of analyzing cardiac information according to claim 1 further comprising:

Sending the collected self-contained portable cardiac monitors to a processing center before the retrieving step.

3. The method of analyzing cardiac information according to claim 1, the forwarding step further comprising:

Electronically sending retrieved cardiac information to a processing center.

4. The method of analyzing cardiac information according to claim 1 further comprising:

Removing a self contained portable cardiac monitor from a mammal before the collecting step.

5. The method of analyzing cardiac information according to claim 1 further comprising:

Analyzing the retrieved cardiac information to identify cardiac events or parameters.

6. The method of analyzing cardiac information according to claim 5 wherein the analyzing step is done after the forwarding step.

7. The method of analyzing cardiac information according to claim 1 wherein the mammal specific information in at least one of the plurality of self-contained, wearable, portable cardiac monitors includes substantially all of the cardiac information from a mammal for at least 7 days.

8. The method of analyzing cardiac information according to claim 1 wherein the cardiac information in the forwarding step includes substantially all of the cardiac information from a mammal for at least 7 days.

9. The method of analyzing cardiac information according to claim 1 wherein the forwarding step includes providing mammal specific cardiac information to a physician identified in the collecting step.

10. The method according to claim 1 further comprising:

Processing information from the forwarding step to determine the presence of an arrhythmia.

11. The method according to claim 1 further comprising:

Processing information from the forwarding step using more than one algorithm to determine the presence of an arrhythmia.

12. The method according to claim 1 further comprising:

Processing information from the forwarding step to evaluate the presence of an arrhythmia during a selected time interval.

13. The method according to claim 12 wherein the information from the forwarding step is processed during the same selected time interval on more than one day.

14. The method according to claim 1 further comprising:

Processing information from the forwarding step to evaluate the presence of an arrhythmia during a time interval indicated by the mammal.

15. The method according to claim 1 further comprising:

Processing information from the forwarding step to determine the presence of an arrhythmia.

16. The method according to claim 1 further comprising:

Providing a user access to information from the retrieving step or the forwarding step so that the user may process the provided information using more than one algorithm to determine the presence of an arrhythmia.

17. The method according to claim 1 further comprising:

Providing a user access to information from the retrieving step or the forwarding step so that the user may process the provided information to evaluate the presence of an arrhythmia during a selected time interval.

18. The method according to claim 17 wherein the provided information is processed during the same selected time interval on more than one day.

19. The method according to claim 1 further comprising:

Providing a user access to information from the retrieving step or the forwarding step so that the user may process the provided information to evaluate the presence of an arrhythmia during a time interval indicated by the mammal.
