It will likely diverge from its normal value because of its increased impact on Starling's Law of the Heart. References: National Library of Medicine. (2024). Physiology, Frank Starling Law.

The most important factors in preload are venous return and the rate of filling. Venous return refers to the amount of blood that returns to the heart during the diastolic phase. The rate of filling refers to the amount of time it takes to fill.
