In this context, caffeine can increase the heart beats of many organisms. Caffeine binds to receptors on the surface of heart muscle cells which leads to an increase in the level of cAMP inside the cells which then increases the heart rate. This creates an overall effect to increase the rate of glycolysis and the amount of ATP available for muscle contraction and relaxation.
Too Much Caffeine. Consuming too much caffeine can cause chest pain, chest tightness and an increased heart rate. Caffeine affects people differently, depending on weight, normal caffeine consumption and other medical conditions. MayoClinic.com states that the average adult can consume between 200 to 300mg of caffeine daily without causing any harm. If you drink 500mg or more, you may develop adverse reactions, such as chest pain.
