System and method for timing synchronized pacing

摘要

A device and method for cardiac rhythm management in which a heart chamber is paced in accordance with sense signals from the opposite chamber or other distant cardiac site. In an exemplary embodiment, a rate chamber and a synchronized chamber are defined. The synchronized chamber is then paced in accordance with a synchronized pacing mode such that a synchronized chamber pace is delivered at a specified pacing instant defined with respect to expiration of a rate chamber escape interval based upon rate chamber events. The method is particularly useful in delivering cardiac resynchronization therapy.
