Heavy pounding of the heart relates more to the force of
contraction which is governed by the amount of catecholoamines (adrenalin) as
well as the volume of blood put out with contraction. Often times this will lead to a faster heart
rate but it doesn’t have to. An example would
be aortic regurgitation wherein the heart is heavily loaded (preload), from
backward filling across aortic valve.
