Causes of Heart Palpitations. Heart palpitations can be caused by any stimulant. Excess caffeine is a common cause of a pounding heart, and some people will experience heart palpitations with even a small amount of caffeine. One cup of coffee can contain 100 to 200 milligrams of caffeine.
Caffeine can increase blood pressure; long term consumption at sufficiently high doses has been associated with chronic arterial stiffness. Blood pressure increases are mediated by adenosine receptor antagonism. Caffeine can cause vasoconstriction. It is unclear if caffeine causes increased heart rate as a side effect.
