WebCardiac output is influenced by heart rate and stroke volume, both of which are also variable. SVs are also used to calculate ejection fraction, which is the portion of the blood that is pumped or ejected from the heart … WebDecreased preload results in decreased stroke volume. An increase in heart rate often maintains cardiac output initially, but when this compensatory response is inadequate, cardiac output diminishes. The formula that defines this relationship is as follows: Cardiac output = Heart rate × Stroke volume
