System and method for cardiac rhythm management with synchronized pacing protection period
First Claim
Patent Images
1. A method for operating a cardiac rhythm management device, comprising:
- sensing rate and synchronized heart chambers through separate channels and generating sense signals upon detection of depolarization occurring in a chamber; and
, pacing the synchronized chamber in accordance with a synchronized pacing mode based upon rate chamber events wherein pacing of the synchronized chamber is inhibited during a synchronized chamber protection period that is initiated by a synchronized chamber sense or pace.

Abstract
A device and method for cardiac rhythm management in which a heart chamber is paced in accordance with a pacing mode that employs sense signals from the opposite chamber. A protection period triggered by the sensing of intrinsic activity in the paced chamber is used to inhibit pacing without otherwise disturbing the pacing algorithm.

11. A cardiac rhythm management device, comprising:
-
sensing channels for sensing depolarizations from heart chambers designated as a rate chamber and a synchronized chamber;
a controller for controlling the delivery of paces in accordance with a programmed pacing mode; and
,wherein the controller is programmed to pace the synchronized chamber in accordance with a synchronized pacing mode based upon rate chamber events and wherein pacing of the synchronized chamber is inhibited during a synchronized chamber protection period that is initiated by a synchronized chamber sense or pace. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
