The physiologic parameters of the normal cardiac cycle are shown here. If the following values are obtained with cardiac catheterization:

• Chamber volume at end of diastole = 0.17 L
• Chamber volume at end of systole = 0.07 L
• Heart rate = 60/min

Stroke Volume = ((Chamber Volume at End Diastole) - (Chamber Volume at End Systole))

Stroke Volume = 0.1 L

Cardiac Output = (Stroke Volume) X (Heart Rate)

Cardiac Output = 6 L/min

Ejection Fraction = ((Stroke Volume) / (Chamber Volume at End Diastole)) * 100

Ejection Fraction = 59%
