Preload from wiki

In cardiac physiology, preload is the pressure stretching the ventricle of the heart after atrial contraction and subsequent passive filling of the ventricle. If the chamber is not mentioned, it is usually assumed to be the left ventricle.

Preload is theoretically most accurately described as the initial stretching of a single cardiac myocyte prior to contraction. This cannot be measured in vivo and therefore other measurements are used as estimates. Estimation is inaccurate, for example in a chronically dilated ventricle new sarcomeres may have formed in the heart muscle allowing the relaxed ventricle to appear enlarged. The term end-diastolic volume is better suited to the clinic, although not exactly equivalent to the laboratory term preload.
