Stroke Volume Can Be Calculated From The Ejection Loop

We have just described an ejection loop for the heart that makes it easy to calculate the output of the heart. For example, the stroke volume is given by:

Stroke volume = end-diastolic volume

In the example shown in Fig. 5, stroke volume is calculated as the difference between points B and C, or 75 mL. The fraction of the contents that the heart ejects is called the ejection fraction and is calculated as the stroke volume divided by the end-diastolic volume, and in this case would be 50% (75/150). Of course, the shape of the systolic and diastolic compliance curves will vary from heart to heart, but if the curves are known for any heart, then its output can accurately be calculated. The next several sections reveal that only three variables affect stroke volume in the normal heart: contractility, venous pressure, and aortic pressure.
