1. A method for stimulating cardiac tissue, comprising:
- providing a plurality of electrodes in at least two different chambers of the heart;
applying bi-ventricular pacing pulses to the heart at multiple sites in at least two different chambers of the heart; and
applying an Excitable Tissue Control (ETC) signal in a vicinity of one or more of the pacing sites located in the left ventricle following application of the pacing pulse at said site.
