This allows direct comparison of the stroke volume index of large and small patients. Stroke volume index is determined by three factors: Preload: The filling pressure of the heart at the end of diastole. Contractility: The inherent vigor of contraction of the heart muscles during systole. Afterload: The pressure against which the heart must work to eject blood during systole. Starling's Law is the relationship between preload and stroke volume .
Stroke volume is the amount of blood that is sent out of the heart during the systole stroke of the heartbeat. This is the combined output of both the left and the right ventricles. For a healthy male, this volume is somewhere around 5.6 liters per hour, for a healthy female, 4.9 liters per hour. The factors that could affect stroke volume would be heart disease, any of which narrow the ventricles chambers. Some of these diseases weaken the muscle of the ventricles, causing a decreased heart rate. Atherosclerosis, or hardening of the arteries, can have a dibilitating effect on cardiac output as well.
