Answer to Question 1

Increases in heart rate shorten all phases of the cardiac cycle. The most important is that the time the heart spends relaxing is less. If the length of time for ventricular relaxation is shortened, there is less time for them to fill adequately with blood. If the ventricles do not have time to fill, the following occur: the amount of blood sent to the coronary arteries is reduced, the amount of blood pumped out of the ventricles will decrease (cardiac output), and signs of myocardial ischemia may be seen.

Answer to Question 2
