In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , , or , is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured per minute). Cardiac output (CO) is the product of the heart rate (HR), i.e. the number of heartbeats per minute (bpm), … WebJun 14, 2024 · Cardiac output is defined as the volume of blood ejected by the heart per unit time. It is usually presented as [stroke volume × heart rate], in L/min. Its main determinants are heart rate and stroke volume. Stroke volume, in turn, is determined by preload afterload and contractility, each of which have their own determinants, and each …
