WebPreload can be defined as the initial stretching of the cardiac myocytes prior to contraction. Preload, therefore, is related to muscle sarcomere length. Because sarcomere length cannot be determined in the intact heart, other indices of preload are used, such as ventricular end-diastolic volume or pressure. When venous return to the heart is ...
