Cardiac output (known as âQâ) is a measure of the amount of blood that is pumped out of the heart in one minute. âQâ specifically refers to the amount of blood pumped out of the left ventricle as this is the ventricle that supplies blood to the muscles and organs of the body.
Preload is defined as the actual stretch or tension on the ventricular myocardium prior to contraction (Totora & Gabowski 2002). The greater the preload on the myocardium (the larger the amount of blood that has filled the heart during diastole), the greater the contraction will be.

It would be pretty cool if Steam allowed you to pre-load games you hadn't pre-ordered, especially right before a sale when you know there's games you'll pick up, but the download servers will be swamped.osts: 4,974. Waiting a few hours is annoying if everyone on the internet is talking about that shiny new game, especially since you did pay that premium to get the game at launch. Also you might want to rethink your scathing attitude towards those impatient suckers.
