Stroke volume refers to the amount of blood ejected by the left ventricle of the heart with each heartbeat. It is not synonymous with pulse rate, which is the number of heartbeats per minute, nor is it directly measured by taking a pulse at the radial or carotid arteries. Pulse measurements can give insights into heart rate but not the volume of blood ejected per beat.
