Optimization of latissimus dorsi isometric force production by N-let electrical stimulation

Abstract

In this paper we present the results of a study on optimal variable frequency 'N-let' stimulation of unconditioned goat latissimus dorsi muscle. The latissimus dorsi is the muscle of choice for both dynamic cardiomyoplasty and skeletal muscle ventricles. Optimized 2-pulse (doublet), 3-pulse (triplet), and 4-pulse (quadlet) bursts were found to provide significantly greater isometric force-time integrals than comparable fixed frequency bursts.
