Abstract
An algorithm executed in an implantable cardiac rhythm management device (CRMD) automatically adjusts the time that an atrial pace (AP) and/or a ventricular pace (VP) pulse is generated by a pulse generator when the expected time of occurrence of the AP pulse falls within a predetermined interval referred to as the “lowest tachy zone”. By delaying the generation of the AP pulse until outside of the lowest tachy zone, undersensing of ventricular tachycardia depolarizations due to cross-channel refractory and VP refractory is avoided.
