Abstract
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. The method is particularly useful in delivering cardiac resynchronization therapy.

A method for operating a cardiac rhythm management device, comprising:
- sensing a site in a heart chamber designated as a rate site and generating a rate site sense upon detection of depolarization occurring at the rate site;
- sensing another site in the same heart chamber designated as a synchronized site and generating a synchronized site sense upon detection of depolarization occurring at the synchronized site;
- pacing the synchronized site at a pacing instant defined with respect to expiration of an escape interval;
- and,
- restarting the escape interval after a rate site sense.

A method for operating a cardiac rhythm management device, comprising:
- sensing a site in a heart chamber designated as a rate site and generating a rate site sense upon detection of depolarization occurring at the rate site;
- sensing another site in the same heart chamber designated as a synchronized site and generating a synchronized site sense upon detection of depolarization occurring at the synchronized site;
- and,
- pacing the synchronized site at a specified trigger interval after a rate site sense.
