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.
Caffeine is probably the TOP reason that people get heart palpitations. Caffeine speeds up the heart and causes it to become more irritable. But it's not JUST the caffeine that causes problems. Many people who get heart palpitations also lace their coffee with sugar or artificial sweeteners, or drink SODAS instead.
