1. An apparatus for minimizing cardiac remodeling of a non-arrhythmic patient comprising:

  • a heart stimulation device comprising control circuitry, wherein the control circuitry is configured with instructions for stimulating cardiac tissue, wherein the cardiac tissue comprises healthy and compromised areas;

    a left ventricular electrode group, wherein the left ventricular electrode group comprises LV electrodes attached to the left ventricle at increasing distances from the AV node; and

    a right ventricular electrode group, wherein the right ventricular electrode group comprises RV electrodes attached to the left ventricle at increasing distances from the AV node,wherein the heart stimulation device is configured to attach to the LV and RV electrodes, and wherein instructions for stimulating cardiac tissue include instructions configured to cause the control circuitry to perform operations comprising;

    generating a timing signal coincident with a refractory period; and

    in response to the timing signal, sending a series of biphasic pulses to the LV and RV electrodes, wherein the series of biphasic pulses is sequenced such that an initial pulse arrives at an LV electrode and an RV electrode nearest the AV junction, and subsequent pulses arrive at an LV and an RV electrode progressively further from the AV junction.
