1. An electrical medical stimulator, comprising:
- electrode means for delivery of electrical stimulation to the fat pad associated with the AV node of a human heart;
pulse generator means for generating stimulus pulses and for providing said stimulus pulses to said first electrode means;
means for sensing occurrences of PVCs; and
means for activating said pulse generator in response to occurrences of PVCs to deliver stimulus pulses to said electrode means, synchronized to said PVCs.

Abstract
A device for controlling the duration of A-V conduction intervals ia a patient'"'"'s heart. Stimulation of the AV nodal fat pad is employed to maintain the durations of the A-V conduction intervals within a desired interval range, which may vary as a function of sensed heart rate or other physiologic parameter. AV nodal fat pad stimulation may also be triggered in response to defined heart rhythms such as a rapid rate or the occurrence of PVC'"'"'s, to terminate or prevent induction of arrhythmias.
