1. A pacing system comprising:

  • a signal generator that provides a first electrostimulation pulse and a second electrostimulation pulse, each electrostimulation pulse having positive and negative signal components, the first and second pulses including at least partially overlapping opposing polarity waveforms to pace a heart from a single chamber of the heart, the electrostimulation provided for delivery via a pacing lead having a first electrode and a second electrode; and

    circuitry for routing at least some of the signal components of the two electrostimulation pulses to the pacing lead by connecting a negative component of a first electrostimulation pulse and a positive component of a second electrostimulation pulse to a common reference and by connecting the positive component of the first electrostimulation pulse to the first electrode and the negative component of the second electrostimulation pulse to the second electrode.
