Described herein are implantable cardiac stimulation devices, and methods for use therewith. A pacing channel of such a device includes a pace output terminal, a pulse generator and at least two pace return electrode terminals. The pace output terminal is coupleable to an electrode for use as an anode. The pulse generator is configured to selectively output an electrical stimulation pulse to the pace output terminal. Each of the pace return electrode terminals is coupleable to a separate one of at least two further electrodes for use as a cathode. Switching circuitry selectively couples any one of the pace return electrode terminals of the pacing channel to the pace return capacitor of the pacing channel at a time, thereby enabling the pace return capacitor to be shared by at least two of the pace return electrode terminals of the pacing channel. Additional embodiments are also disclosed herein.
