Abstract:
1. A cardiac rhythm management device, comprising: sensing and pacing circuitry connectable to a right ventricular electrode and a left ventricular electrode to form right and left ventricular pacing and sensing channels; a controller connected to the sensing/pacing circuitry and programmed to: generate a right ventricular sense upon detection by the right ventricular electrode of a depolarization occurring in the right ventricle; pace the left ventricle by delivering a pacing pulse to the left ventricular electrode upon expiration of an escape interval; restart the escape interval a ter a right ventricular sense, wherein the escape interval unaffected by depolarization occurring in the left ventricle and detected by the left ventricular electrode; render the right and left ventricular sensing channels refractory for a selected pacing refractory period after delivery of a left ventricular pace; and render the right ventricular sensing channel refract for a selected sensing refractor period after generation of a right ventricular sense while leaving the left ventricular sensing channel non-refractory.
