The amount of blood ejected from heart for one cardiac cycle is the stroke volume index. The heart rate is the number of times the heart beat per minute. Blood pressure is affected by cardiac output and resistance. The blood flow is constant throughout the body, but varies in the individual organs. A normal heart rate for adult varies form 60 to 100 beats per second. Dividing the cardiac index by the heart rate is the cardiac stroke volume index formula.
Healthy cardiovascular system will have lower heart rate. Find your stroke volume index by entering the cardiac index and heart rate in the cardiac stroke volume index formula.
