Method and system for display of cardiac event intervals in a resynchronization pacemaker
First Claim
Patent Images
1. An external programmer for a pacemaker having a plurality of sensing/pacing channels, comprising:
- a telemetry interface for communicating with the pacemaker;
a display;
wherein the external programmer is configured to receive signals from the pacemaker and display markers representing sensing and pacing events spaced in accordance with their time sequence, wherein each marker indicates whether the event is a sense or a pace and in which channel the event occurred; and
,wherein the external programmer is configured to display an interval value with each marker for a first channel indicating the time interval between the event represented by the marker and the preceding first channel event, and display an interval value with each marker for a second channel indicating the time interval between the event represented by the marker and a nearest first channel event.

Abstract
A cardiac rhythm management system that includes a pacemaker configured for biventricular pacing and an external programmer with an associated display for displaying electrogram data and markers representing ventricular events. Associated with each marker are intraventricular intervals designed to relate information to a user in a manner suited for ventricular resynchronization pacing.

9. A cardiac rhythm management system, comprising:
-
a pacemaker having a plurality of sensing amplifiers and pulse generators for sensing cardiac activity and delivering pacing pulses through a plurality of sensing/pacing channels, a controller for controlling the delivery of paces in accordance with a programmed pacing mode, and a telemetry interface for transmitting signals representing sensing and pacing events; an external programmer with an associated display, wherein the programmer is configured to receive the signals transmitted by the pacemaker and output markers representing sensing and pacing events on the display spaced in accordance with their time sequence, wherein each marker indicates whether the event is a sense or a pace and in which channel the event occurred; and
,wherein the external programmer is configured to display an interval value with each marker for a first channel indicating the time interval between the event represented by the marker and the preceding first channel event, and display an interval value with each marker for a second channel indicating the time interval between the event represented by the marker and a nearest first channel event. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
