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 (19)

1. A method of analyzing cardiac rhythm information, the method comprising:

collecting a plurality of self-contained, wearable, portable cardiac monitors, each of the cardiac monitors removed from a different mammal after having been worn by each mammal continuously without removal for at least 24 hours, and each of the cardiac monitors including at least two electrodes, an action sequencer having no central processing unit for rhythm analysis, and a memory containing at least 24 hours of continuously detected, stored and unanalyzed cardiac rhythm information, comprising both normal cardiac rhythm information and abnormal cardiac rhythm information collected from the mammal, wherein each cardiac monitor includes a watertight housing enclosing at least the action sequencer and the memory electronically coupled with the electrodes;

opening the watertight housing on each cardiac monitor to retrieve the at least 24 hours of continuously detected, stored cardiac rhythm information stored in each of the collected plurality of self-contained portable cardiac monitors;

analyzing, after the retrieving step, the at least 24 hours of continuously detected, stored cardiac rhythm information to generate a report; and

providing the report to a user.

2. The method of analyzing cardiac rhythm information according to claim 1 , wherein the analyzing step comprises electronically sending the retrieved cardiac rhythm information to a processing center.

3. The method of analyzing cardiac rhythm information according to claim 1 , wherein the analyzing step comprises analyzing the at least 24 hours of continuously detected, stored cardiac rhythm information to identify cardiac events or parameters.

4. The method of analyzing cardiac rhythm information according to claim 1 , wherein at least a majority of the plurality of self-contained, wearable, portable cardiac monitors includes substantially all of the continuously detected, stored cardiac rhythm information from a mammal for at least 7 days.

5. The method of analyzing cardiac rhythm information according to claim 1 , wherein the retrieved cardiac rhythm information includes substantially all of the cardiac rhythm information from a mammal for at least 7 days.

6. The method of analyzing cardiac rhythm information according to claim 1 , wherein the providing step includes providing retrieved cardiac rhythm information to a physician identified in the collecting step.

7. The method according to claim 1 , wherein the analyzing step comprises analyzing the at least 24 hours of continuously detected, stored cardiac rhythm information to determine the presence of an arrhythmia.

8. The method according to claim 7 , wherein analyzing comprises using more than one algorithm to determine the presence of the arrhythmia.

9. The method according to claim 1 , wherein the analyzing step comprises analyzing the at least 24 hours of continuously detected, stored cardiac rhythm information to evaluate the presence of an arrhythmia during a selected time interval.

10. The method according to claim 9 , wherein the cardiac rhythm information is processed during the same selected time interval on more than one day.

11. The method according to claim 1 , wherein the analyzing step comprises analyzing the at least 24 hours of continuously detected, stored cardiac rhythm information to evaluate the presence of an arrhythmia during a time interval indicated by the mammal.

12. The method according to claim 1 , wherein the analyzing step comprises providing the at least 24 hours of continuously detected, stored cardiac rhythm information to a user so that the user may process the provided information using more than one algorithm to determine the presence of an arrhythmia.

13. The method according to claim 1 , wherein the analyzing step comprises providing the at least 24 hours of continuously detected, stored cardiac rhythm information to a user so that the user may process the provided information to evaluate the presence of an arrhythmia during a selected time interval.

14. The method according to claim 13 wherein the provided information is processed during the same selected time interval on more than one day.

15. The method according to claim 1 , wherein the analyzing step comprises providing the at least 24 hours of continuously detected, stored cardiac rhythm information to a third party so that the third party may process the provided information to evaluate the presence of an arrhythmia during a time interval indicated by the mammal prior to the collecting step.
