An increase in the heart rate can be caused by a number of things. One is the increase in the blood coming back from the body to the heart. The increased volume of blood stretches the heart muscles causing a "reflex" increase in heart rate to accommodate the increased need for oxygen such as in the case of exercise. Another one could be the sympathetic control of the brain such as in periods of anxiety, fear or anger. Drugs can also increase your heart rate.
