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 of depolarization above a specified threshold occurring in the right ventricle; generate a left ventricular sense upon detection of depolarization above a specified threshold occurring in the left 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 after a right ventricular sense; 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 refractory for a selected sensing refractory period after generation of a right ventricular sense while leaving the left ventricular sensing channel non-refractory.
