1. A method, comprising:

  • identifying a vulnerable ventricular region in a patient that is predisposed to becoming ischemic;

    implanting a cardiac pacing device having first and second electrodes;

    implanting the first electrode near the ventricular region vulnerable to ischemia so that a pacing pulse from the first electrode unloads the vulnerable region during systole as compared with an intrinsic beat;

    implanting the second electrode near a ventricular region remote from the vulnerable region so that a pacing pulse from the second electrode loads the vulnerable region during systole as compared with an intrinsic beat;

    configuring the device to operate in a vulnerable region unloading mode that delivers pacing pulses through a pacing channel configured with the first electrode; and

    ,configuring the device to intermittently operate in a vulnerable region loading mode that delivers pacing pulses through a pacing channel configured with the second electrode.
