1. An apparatus for determining whether ventricular pacing stimuli are capturing a paced ventricle, comprising:
delivering means for delivering the ventricular pacing stimuli to the paced ventricle;
sensing means for sensing signals in response to delivery of the ventricular pacing stimuli;
processing means, responsive to the sensing means, for determining whether individual ones of the ventricular pacing stimuli effectively captured the paced ventricle over a series of the ventricular pacing stimuli, the determination comprising determining whether a defined number of the individual ones of the series effectively captured the paced ventricle; and
modifying means for modifying a pacing rate during atrial fibrillation in response to the defined number of the individual ones of the series having effectively captured the paced ventricle and not modifying the pacing rate during atrial fibrillation in response to the defined number of the individual ones of the series having not effectively captured the paced ventricle.
