ABSTRACT:
A cardiac rhythm management device is disclosed which incorporates an improved method for sensing atrial depolarizations during episodes of ventricular tachycardia. The atrial sensing channel is blanked for a specified blanking interval after detection of a ventricular sense. When the ventricular rate is above a specified limit rate, the blanking interval for the atrial sensing channel is either shortened or blanking is discontinued altogether in order to allow sensing of atrial depolarizations that occur shortly after a ventricular sense.
