Preload can still be approximated by the inexpensive echocardiographic measurement end-diastolic volume or EDV. Preload increases with exercise (slightly), increasing blood volume (as in edema, excessive blood transfusion (overtransfusion), polycythemia) and neuroendocrine activity (sympathetic tone). An arteriovenous fistula can increase ...
Preload is an engineering term with several meanings. In the general sense, it refers to the internal application of stress to certain mechanical systems. In the general sense, it refers to the internal application of stress to certain mechanical systems.
The three curves illustrate that shifts along the same line indicate a change in preload, while shifts from one line to another indicate a change in afterload or contractility. A blood volume increase would cause a shift along the line to the right, which increases left ventricular end diastolic volume (x axis), and therefore also increases ...
Because greater EDVs cause greater distention of the ventricle, EDV is often used synonymously with preload, which refers to the length of the sarcomeres in cardiac muscle prior to contraction . An increase in EDV increases the preload on the heart and, through the Frank-Starling mechanism of the heart, increases the amount of blood ejected ...

Preconsolidation pressure is the maximum effective vertical overburden stress that a particular soil sample has sustained in the past. [1] This quantity is important in geotechnical engineering, particularly for finding the expected settlement of foundations and embankments.
