Answer 2

The most common changes in heart rate are (Note: The factors below are the causes for heart rate to increase):

• Age: Infants hearts beat much faster than a child's or an adults heart. For example, an infants heart can beat between 120 and 150 times per minute and a child's heart can beat between 80-110 times per minute (adult rate: 60-80 beats per minute).
• Stress levels: The more stressed a person is, the more likely an increase in the heart rate.
• Exercise: The more exercise a person does, for example running, the higher the heart rate.
• Drugs: Many, if not all drugs, cause an increase in heart rate.
• Fear/panic: The more afraid a person is, the higher the heart rate.
• Excitment: Excitement may also cause an increase in heart rate.

These are the main factors that cause a person's heart rate to increase.

Answer 3

Rest, sleep, exercise and excitement.

In terms of the physiological change, the pulse rate is dependant on the heart rate. This is self-perpetuating (it stays at the same rate unless it is signalled to speed up or slow back down). This signal is sent from the medulla to the SAN (sino-atrial node, or 'pacemaker') to increase or decrease the rate of the heart, and so the pulse rate.
