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 .
Cardiac output = stroke volume Ã heart rate. Your stroke volume is the amount of blood your heart pumps each time it beats, and your heart rate is the number of times your heart beats per minute. A healthy heart with a normal cardiac output pumps about 5 to 6 liters of blood every minute when a person is resting.
