Cardiac output is the blood volume pushed out by the left ventricle per minute.

Stroke volume is the volume of blood pushed out of the left ventricle per contraction of the heart (each heart beat). So stroke volume into heart rate / minute gives you cardiac output.

Stroke Volume is the volume of blood that is ejected with each contraction of the heart.

Cardiac output is the total volume of blood that is ejected from the heart per minute.

Cardiac output = Stroke Volume x Heart Rate

Which statement is correct about cardiac output?

cardiac output is heart rate multiplied by stroke volume,


What does cardiac output do if the heart rate decreases?

Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.


How does tachycardia affect stroke volume and cardiac output?

What effects cardiac output during the first few stages of exercise?

Cardiac Output is computed as your heart rate times your stroke volume (volume of blood ejected from the heart each beat). The main contributor when exercising is an acceleration in heart rate. Stroke volume can be increased, but only by prolonged aerobic training. To answer your Q, HR as has the main effect on cardiac output during the first stages of exercise.**The first few stages of cardiac exercise will 'affect' cardiac output, not 'effect' it. If you don't know the difference between the two, you should not be asking a question such as this...


How would a decrease in blood volume affect both stroke volume and cardiac output?

It's decreased ... unless the rate falls, which is the normal cardiac response.


What is the formula for calculating cardiac output?

What does heart rate and stroke volume determine?

cardiac output


Does the cardiac output equal heart rate multiplied by stroke volume?

Yes. CO = HR x SV CO - cardiac output HR - heart rate SV - stroke volume


Is stroke volume usually larger than cardiac output?

FALSE


Would an increase in contractility cause an increase to cardiac output?

Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.


What is cardiac-output?

Cardiac output is the volume of blood the heart pumps within one minute. Cardiac output (CO) is equal to the stroke volume (SV) of the heart multiplied by the heart rate (HR). Thus, cardiac output is given by the equation: CO=HR X SV.
