Adrenaline: The heart rate is controlled by a balance of sympathetic and parasympathetic fibers. Adrenaline mediate sympathetic responses and via beta receptors on the heart cells leads to speeding up of the heart rate. Additionally anticholinergic medications can break the vagal tone which mediates the parasympathetic tone that normally slows heart rate.
