In a cardiomyoplasty system, a rate responsive implantable device is disclosed which controls the stimulation of both the heart and a myoplasty muscle. The metabolic demand is used as a rate response parameter and one or both of the heart and the muscle stimulation are increased with metabolic demand. Under certain conditions, for example, if the muscle is tired, its stimulation is maintained constant or reduced and the cardiac stimulation is used to compensate for increased metabolic demand.

Myostimulator control using metabolic demand and muscle performance

A cardiomyoplastic muscle is stimulated electronically using a closed loop control system. As part of the system, a signal sensed the muscle which is characteristic of its condition. If this signal indicates an abnormal condition, then the stimulation of the muscle is modified accordingly.

Cardiomyoplasty simulator with feedback control

A pacemaker or similar cardiac and cardiomyoplasty muscle stimulator is provided which during a training period of said muscle, defining alternating training and augmentation phases. During training phases training pulses are provided for the muscle until the muscle is capable of performing cardiac assistance for relatively extended time periods. During the augmentation phases, augmentation pulses are applied to the muscle to provide cardiac assistance even with a muscle with no, or limited training.
