Method and system for display of cardiac event intervals in a resynchronization pacemaker
First Claim
1. A method for displaying electrogram data collected by a pacemaker where one heart chamber is paced through a rate sensing/pacing channel and another site in the same or contralateral chamber is paced through a synchronized sensing/pacing channel with the pacing mode being based upon senses and paces in the rate channel, comprising:
- displaying markers representing sensing and pacing events spaced apart 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;
displaying an interval value with each rate channel marker indicating the time interval between the event represented by the marker and the preceding rate channel event; and
, displaying an interval value with each synchronized channel marker indicating the time interval between the event represented by the marker and a nearest rate 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.

15. A cardiac rhythm management system, comprising:
-
a pacemaker having a rate sensing/pacing channel and a synchronized sensing/pacing channel, a controller for controlling the delivery of paces in accordance with a pacing mode based upon rate channel events, and a telemetry interface for transmitting signals representing rate and synchronized channel events;
an external programmer with an associated electronic display or print output, 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 rate channel marker indicating the time interval between the event represented by the marker and the preceding rate channel event, and display an interval value with each synchronized channel marker indicating the time interval between the event represented by the marker and a nearest rate channel event.
