WebJun 14, 2024 · The heart being a pump which functions in a pulsatile fashion, it is possible to describe the cardiac output in terms of stroke volume and heart rate. Cardiac output = stroke volume × heart rate Beyond this, stroke volume has several determinants, which are: Cardiac contractility Preload Afterload Men, on average, have higher stroke volumes than women due to the larger size of their hearts. However, stroke volume depends on several factors such as heart size, contractility, duration of contraction, preload (end-diastolic volume), and afterload. Corresponding to the oxygen uptake, women's need for blood flow does not decrease and a higher cardiac frequency makes up for their smaller s…
