Venous return is affected by several factors including muscle contraction, respiratory activity and gravity. Decreased venous compliance and vena cava compression also influence venous return. Other factors include valve competence, heartbeat, intrapericardial pressure, blood volume and degree of filling systematic circulation.
ESV can be affected by 4 factors; preload, afterload, contractility, and Heart rate, and EDV also depends on 3 factors; venous return, Heart rate, and compliance. 1  Preload (ie, the EDV):The more cardiac muscle is stretched, the harder it contracts (Frank & Starling's law). 2  Positive agents: 3  Slow heart rate, 4  exercise.
