A first electrical pulse and a second electrical pulse are transmitted to one or more implanted leads (16, 18) including first and second electrodes (16A, 18A), respectively. The first and second pulses have a timing relationship such that the combined potentials induce action potentials in a certain locus of electrically excitable tissue (12). Means are provided for adjusting the timing relationship and pulse parameters so that the locus is altered. |
