Abstract

Systems, devices and methods for defining, identifying and using health-related significant events are disclosed. One aspect is a programmable device having machine executable instructions for performing a method to assist with managing a patient'"'"'s health. In various embodiments, at least one previously-defined event is detected based on a number of acquired health-related parameters. The at least one detected event is recorded with an associated time when the at least one detected significant event occurred. An action is triggered based on the at least one detected event. The at least one detected event is displayed with at least one trended health-related parameter in a single display area. Other aspects and embodiments are provided herein.

14. The device of claim 1, wherein the method performed by the device further comprises acquiring one or more of the number of acquired health-related parameters using at least one manual data input.

15. The device of claim 11, wherein the method performed by the device further comprises acquiring the number of acquired health-related parameters using the at least one implantable medical device (RID) sensor and further using:

at least one external sensor;

at least one external data source;

or

at least one manual data input.

16. The device of claim 1, wherein recording the at least one detected event with an associated time includes recording a time stamp for use in temporally comparing the at least one detected event with the at least one trended health-related parameter.

17. The device of claim 1, wherein triggering an action based on the at least one detected event further includes changing a device therapy based on the at least one detected event.

18. The device of claim 1, wherein triggering an action based on the at least one detected event further includes providing an alarm based on the at least one detected event.

19. The device of claim 1, wherein the at least one trended health-related parameter displayed with the at least one detected event is used to detect the at least one defined event.

20. The device of claim 1, wherein the at least one trended health-related parameter displayed with the at least one detected event is not used to detect the at least one defined event.
