How does caffeine affect heart rate?

Caffeine in high doses raises your blood level of epinephrine. Epinephrine is also known as adrenalin. In pure forms, epinephrine can increase blood pressure, increase the contractility or force of the heart, and mildly increase the heart rate.

Why does caffeine lower my heart rate?

Moderate doses of coffee have been shown to reduce resting heart rate due to a moderate increase in BP. The decrease in heart rate is generally associated with vagally mediated slowing as the baroreceptors respond to BP elevations after caffeine administration.

How does caffeine affect heart rate during exercise?

A cardiovascular stimulant, caffeine affects the heart directly by causing andrenergic nerve terminals in the heart and adrenal medulla to release more catecholamines. It has both positive inotropic (i.e., strength of contraction) and chronotropic (i.e., increased heart rate ) effects.
