Pace counter isolation for cardiac resynchronization pacing
First Claim
Patent Images
1. A method for operating a cardiac rhythm management device, comprising:
- sensing depolarizations and delivering paces to multiple sites of a heart chamber through a plurality of sensing/pacing channels, wherein the heart chamber is paced in accordance with a pacing mode in which a pace is delivered upon expiration of an escape interval or as a result of a triggering event; and
for at least some of the plurality of sensing/pacing channels, separately counting the number of senses received, the number of paces delivered by reason of expiration of an escape interval, and the number of paces triggered by a triggering event.
