1. A system comprising:
a ventricular pacing device configured for implantation entirely within a ventricle of a heart, the ventricular pacing device configured to sense intrinsic ventricular depolarizations and one of:
inhibit delivery of pacing pulses responsive to sensed intrinsic ventricular depolarizations; or
deliver pacing pulses to the ventricle responsive to an absence of sensed intrinsic ventricular depolarizations; and
an atrial pacing device configured for implantation entirely within an atrium of the heart, the atrial pacing device being operable without receiving communication from the ventricular pacing device and being configured to:
detect ventricular activation events; and
deliver pacing pulses to the atrium, each pacing pulse of the pacing pulses being timed based on when respective ventricular activation events are detected by the atrial pacing device.
