Page 1 Stroke Volume Stroke Volume syllabus | home page | BME Home Page | search the web | e-mail Doug Stoke volume is the amound of blood that is pumped out of the heart at every beat. There are two ways to find Stroke volume. If the cardiac output and the heart is known, the stroke volume can be found using this equation: stroke volume = cardiac output / heart rate. Another way to determine the Stroke volume is to subtrack the end systolic volume from the end diastolic volume. Thus you take the volume at the end of relaxation, and subtract the amount of blood that is left in the heart after contraction. Both end diastolic volume and end systolic volume effect the stroke volume. The can be effected by the amount of venous flow into the heart, the heart rate, total peripheral resistance, starlings law, and ventrical contractility. Sample Problems: Question #1: If a heart fills up to 200ml of blood before contraction, and leaves 50ml in the heart after contraction, what is the stroke volume? If heart rate was 80 beats per minute, what would the cardiac output be? Question #2:
