Abstract

A system and method for an implantable cardiac pacing device provide for delivery of anti-tachycardia pacing of the atrium upon detection of atrial tachycardia combined with automatic re-synchronization of ventricular pacing directly following the last atrial pulse of the anti-tachycardia scheme. At the onset of delivery of the ATP train or like scheme of ATP, an appropriate ventricular pacing interval is calculated to enable asynchronous pacing of the ventricle during the ATP and synchronous delivery of the next ventricular pulse at a delay following the end of the ATP train. Upon determination of AT, an algorithm is used to calculate if a ventricular pacing interval can be found that meets maximum and minimum pacing criteria and also provides that the next ventricular pace pulse following the end of the ATP train will follow the last atrial pulse of the train by a suitable AV delay. If such a suitable pacing interval is found, the ventricular pacing interval is set to a temporary value and the train is delivered. If such a pacing interval cannot be initially determined the system waits for one more atrial sense and then repeats the determination to find such a suitable ventricular pacing interval.
