Systole refers to the contraction of muscle fibers in the myocardium, diastole refers to relaxation of the fibers in the myocardium, stroke volume is the volume of blood ejected from the heart during the cardiac cycle. Finally the cardiac cycle refers to all of the aforementioned items and is the entire cycle of the heart from systole to diastole. Mike Branch HAMILTON ISLAND EMERGENCY RESPONSE TEAM.

Do reductions in Venus return cause reductions in both stroke volume and cardiac output?
Yes
What compensations does the body have to do to defend cardiac output if you hemorrhage?

What effect does stimulation of the acetylcholine receptors of the heart have on cardiac output?
The effect would be an increase in cardiac output. However, there is a maximum level and then the heart would not have time to fill fully and the output would decrease.

What measures the force of the heart?
The blood pressure & the cardiac output.
Determined by heart rate x stroke volume?
cardiac output
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?
Lowers stroke volume
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 difference between stroke volume and cardiac output?
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.
What is the formula for calculating cardiac output?
CO=HRXSV, Where HR is heart rate and SV is stroke volume
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.
