Heart rate is controlled beat by beat by the brain. Infact the native rate of the heart (the sinus nodal rythym) is around 100 beats per minute. The parasympathetic supply to the heart (through vagus nerve) supresses the rate to around 70-80. So if the parasympathetic flow is supressed, the heart rate will accelerate.
