Abstract:
A pacing system for pacing a patient's heart during a supraventricular arrhythmia comprising:means for sensing ventricular depolarizations; pulse generation means for timing a ventricular rate regularization escape interval from a sensed ventricular depolarization or a previously delivered ventricular pacing pulse, and for providing ventricular pacing pulses to a ventricle of the heart in a ventricular rate regularization mode at a ventricular rate regularization pacing rate wherein a ventricular pacing pulse is delivered upon expiration of the ventricular rate regularization escape interval; means for retaining a ventricular event sequence of at least two previous ventricular events, each of said events being one of a ventricular pacing pulse and a sensed ventricular depolarization; and regularization means for establishing said ventricular rate regularization pacing rate according to the pattern of events included in the ventricular event sequence.
