GRADUALLY SYNCHRONIZED SIMULTANEOUS ATRIAL AND VENTRICULAR PACING FOR CARDIAC RHYTHM DISCRIMINATION

摘要

A cardiac medical device used for delivering anti-tachycardia pacing in both the atrial and ventricular regions in a simultaneous manner, while preventing potential of inducing atrial arrhythmia. The pacing pulses may be synchronized in a gradual manner so that simultaneous delivery of the pulses is ultimately achieved at reduced risk of inducing atrial arrhythmia. The pacing pulses may also be synchronized immediately after a determination is made whether simultaneous pacing pulses will be delivered in the vulnerable regions of the cardiac cycle.
