Abstract:
1. A cardiac rhythm management device, comprising: an atrial sensing channel for sensing atrial electrical activity; an atrial pacing channel for delivering atrial pacing pulses; a shock pulse generator for delivering atrial defibrillation shocks; a controller programmed with executable instructions for performing functions which include: detecting atrial fibrillation; delivering an atrial defibrillation shock after atrial fibrillation is detected; delivering atrial pacing pulses in accordance with a pacing mode for a specified period of time following an atrial defibrillation shock in which atrial pacing pulses are delivered upon expiration of an atrial escape interval that is dynamically adjusted by decreasing the escape interval when an atrial sense is detected and increasing the escape interval after each paced beat; and, delivering one or more non-excitatory stimulation pulses to an atrium during an atrial refractory period after an atrial pacing pulse.
