Abstract

An implantable cardiac stimulation device operates according to a first pacing algorithm executable by a microprocessor and which is able to independently perform stimulation therapy for a patient's heart, as well as according to a second pacing algorithm which is also microprocessor-executable. The first and second algorithms actively generate stimulation parameters during each cardiac cycle, but the stimulation parameters generated by the second algorithm are only permitted to result in actual stimulation therapy if those parameters fall within parameter ranges that are calculated to be allowable for stimulation by the first algorithm.
