1. A method for biventricular pacing, the method comprising:

  • a) supplying a pacing pulse to a unipolar lead adapted for stimulation of a left ventricle;

    b) supplying a pace pulse to a second lead adapted for stimulation of a right ventricle;

    c) configuring the second lead to provide an anode for the unipolar lead; and

    d) constructing the pace pulse to the unipolar lead to comprise a trailing edge having slope of sufficiently small magnitude to inhibit capture of the right ventricle by anode break stimulation at the anode.
