Abstract
System, device and method of variable pacing and stimulation are provided. In one example device, one or more lead integrated circuits may programmably control one or more variability parameters. One or more electrodes may provide electrical stimulation. Each electrode may be individually addressable by at least one of the lead integrated circuits and controlled by at least one variability parameter. Electrodes may be intentionally shorted together during time intervals that fall between times of stimulus, so as to dissipate potentials that might otherwise persist and cause electrode degradation.
