Implantable cardiac stimulation devices configured to deliver more than one pacing pulse per cardiac cycle, and methods for use therewith, are described herein. A method can include delivering a first pacing pulse using a first pair of electrodes. Thereafter, between delivery of the first pacing pulse and delivery of second pacing pulse using a second (different) pair of electrodes, one or more voltage characteristics are measured at each of a plurality of different nodes within the cardiac stimulation device. A preferred pair of nodes for use during a fast discharge phase are identified based on the measured voltage characteristic(s). Switches within the implantable cardiac stimulation device are controlled so that the pair of nodes, identified as being the preferred pair of nodes that are to be used for performing the fast discharge phase, are used for performing the fast discharge phase to thereby achieve charge neutrality in an improved manner.
