If the heart rate increases, the rate of blood delivery also increases. This occurs because an increase in heart rate means that the heart is beating faster, which in turn pumps blood more frequently. To understand this concept, you can visualize the heart as a pump that pushes blood throughout the body. The more times the pump contracts in a given time period, the more blood is delivered to the various tissues and organs. Therefore, when the heart rate increases, the rate of blood delivery also increases.
