Regulation of Heart Rate
The rate at which the heart beats is modulated by the autonomic nervous system. Baroreceptors, nerve endings in the aortic arch and the carotid arteries, are sensitive to arterial blood pressure. If it's too low or too high, they send signals to the brain, which in turn causes your heart rate to increase or decrease and the arteries to constrict or dilate as necessary to control blood pressure.
