What is Anticipatory Rise?
A slight increase in heart rate usually before activity starts due to the expectation of exercise
What is cardiac output?
The amount of blood the heart pumps out per minute. Measured in Litres
What is the equation for cardiac output?
Cardiac output = Stroke Volume x Heart Rate
Q = SV x HR
What is systole?
The contraction phase of the cardiac cycle. The ventricles contract and blood is pumped into the arteries
What is diastole
The relaxation phase of the cardiac cycle. The ventricles relax and fill with blood
