Patent ID: 7689279

Claim:
A cardiac pacing device comprising: an atrial lead and an atrial electrode mounted with respect to the atrial lead; a ventricular lead and a ventricular electrode mounted with respect to the ventricular lead; a sensor, operatively coupled to at least one of the atrial electrode and the ventricular electrode, sensitive to an atrial arrhythmia; pulse generation circuitry connected to the atrial and ventricular electrodes delivering an anti-tachycardia pacing (ATP) therapy in response to the atrial arrhythmia comprising a plurality of atrial pulses defined by at least one atrial pacing parameter and a plurality of ventricular pulses defined by at least one ventricular pacing parameter and a synchronous therapy following a termination of the anti-tachycardia pacing (ATP) therapy, the synchronous therapy comprising a plurality of atrial pulses and a corresponding plurality of ventricular pulses, each of the ventricular pulses having a predetermined timing relationship following a corresponding one of the plurality of atrial pulses; and control circuitry operatively coupled to the pulse generation circuitry adjusting a priori at least one of the at least one atrial pacing parameter and the at least one ventricular pacing parameter, based on the at least one atrial pacing parameter and the at least one ventricular pacing parameter, to make a last individual one of the plurality of ventricular pulses approximately coincident with a last individual one of the plurality of atrial pulses at the termination of the anti-tachycardia pacing (ATP) therapy.
