Abstract
Any analysis of cardiac relaxation requires an understanding of the role of the sarcoplasmic reticulum (SR) in removing activator Ca2+ from the cytosol at the end of systole. The precise relationship between Ca2+ uptake into this intracellular membrane system and the changes in muscle length and tension that occur during diastole remains incompletely understood, but it is generally accepted that relaxation begins when cytosolic Ca2+ is reduced by the calcium pump of the SR.
