Event marker alignment by inclusion of event marker transmission latency in the real-time data stream
First Claim
1. An implantable cardiac rhythm management (CRM) device comprising:
- at least one sensing circuit, configured for receiving at least one heart signal from a heart;
a processor, configured to process information obtained from the at least one heart signal to generate a substantially real-time event marker and a substantially real-time electrogram; and
at least one communication circuit, configured to communicate the substantially real-time event marker and the substantially real-time electrogram from the implantable CRM device, in which the event marker includes a timestamp relating at least in part to an approximate time between an event associated with the event marker and another event associated with another event marker for aligning an indication of the event marker to a substantially real-time representation of a heart signal on one of a display or a recording that is remote from the implantable CRM device.

Abstract
A cardiac rhythm management system transmits event markers from an implantable device to a remote user interface such as an external programmer. The event markers include timestamp information. A printed/displayed event marker representation is aligned to a printed/displayed heart signal representation based at least in part on the timestamp information. Proper alignment of the printed/displayed heart signal representation to the printed/displayed event marker, and proper alignment of the printed/displayed event markers with respect to each other, provides more accurate diagnostic information to the caregiver. This assists the caregiver in using the cardiac rhythm management system to provide a patient with proper cardiac rhythm management therapy.

- 10. A remote user interface (UI) for an implantable cardiac rhythm management (CRM) device, wherein the UI is adapted to be communicatively coupled to the CRM device for receiving a substantially real-time event marker and a substantially real-time electrogram therefrom, in which the event marker includes a timestamp relating at least in part to an approximate time between an event associated with the event marker and another event associated with another event marker, and based at least in part on the timestamp, the UI aligns an indication of the event marker to a substantially real-time representation of a heart signal on one of a display or a recording.

23. An system comprising:
an implantable cardiac rhythm management (CRM) device, including at least one sensing circuit, configured for receiving at least one heart signal from a heart; a processor, configured to process information obtained from the at least one heart signal to generate a substantially real-time event marker and a substantially real-time electrogram; and means for communicating the substantially real-time event marker and the substantially real-time electrogram from the implantable CRM device, in which the event marker includes a timestamp relating at least in part to an approximate time between an event associated with the event marker and another event associated with another event marker for aligning an indication of the event marker to a substantially real-time representation of a heart signal on one of a display or a recording that is remote from the implantable CRM device. - View Dependent Claims (24)
- 25. A remote user interface (UI) for a cardiac rhythm management (CRM) device, the user interface adapted to be communicatively coupled to the CRM device for receiving a substantially real-time event marker therefrom, in which the event marker includes a timestamp relating at least in part to an approximate time between an event associated with the event marker and another event associated with another event marker, and based at least in part on the timestamp, the UI aligns an indication of the event marker to a substantially real-time representation of a heart signal on one of a display or a recording, and in which the UI also aligns the indication of the event marker to the representation of the electrogram signal based on a fixed delay.

28. A remote user interface (UI) for a cardiac rhythm management (CRM) device, the user interface adapted to be communicatively coupled to the CRM device for receiving a substantially real-time event marker therefrom, in which the event marker includes a timestamp relating at least in part to an approximate time between an event associated with the event marker and another event associated with another event marker, and based at least in part on the timestamp, the UI aligns an indication of the event marker to a substantially real-time representation of a heart signal on one of a display or a recording, and in which the UI is adapted to receive data from the CRM device in frames, in which each data frame includes a plurality of data slots including:
-
a first data slot associated with a first event marker associated with a first electrode; and a second data slot associated with a second event marker associated with a second electrode different from the first electrode. - View Dependent Claims (29, 30, 31)

32. A remote user interface (UI) for a cardiac rhythm management device, the user interface adapted to be communicatively coupled to the CRM device for receiving a substantially real-time event marker therefrom, in which the event marker includes a timestamp relating at least in part to an approximate time between an event associated with the event marker and another event associated with another event marker, and based at least in part on the timestamp, the UI aligns an indication of the event marker to a substantially real-time representation of a heart signal on one of a display or a recording, and in which the timestamp relates at least in part to an approximate time between an event associated with the event marker and the transmission completion time associated with a previous event marker associated with the same heart chamber.
