IS A HEART RATE ALWAYS HIGH IF YOUR HEART IS POUNDING OR CAN IT HAPPEN WHEN IT'S LOW TO NORMAL TOO?

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.
