Abstract
Summary The amout of bound calcium and force were measured in chemically skinned rat myocardial fibers during isometric contraction at different concentrations of free Ca2+. The data obtained suggest that calcium binding by cardiac myofibrils is cooperative and probably depends on mechanical tension.Keywords
