WebSummary: Factors Affecting Stroke Volume (SV) Multiple factors impact preload, afterload, ... WebPreload is, in simplest terms, the stretching of ventricles. Ventricles tend to stretch (fill with blood) and squeeze (push out blood) to distribute blood adequately. However, if too much pressure is backed up due to cardiac …
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 … WebMar 11, 2024 · Consequently, the factors affecting cardiac output are heart rate, contractility, preload, and afterload, the last three of which do so through changing stroke volume.

Ventricular stroke volume (SV) is often thought of as the amount of blood (mL) ejected per beat by the left ventricle into the aorta (or from the right ventricle into the pulmonary artery). This assumes, however, that all the blood leaving the ventricle is ejected into the outflow tract, but this is not the case ...
