The process by which the presence of epinephrine or norepinephrine in the bloodstream activates, maintains or increases the rate of heart contraction. The process by which the secretion of epinephrine into the bloodstream or released from nerve endings increases the rate of heart muscle contraction. The process by which the secretion of norepinephrine or epinephrine into the bloodstream modulates the force with which blood passes through the circulatory system. The process by which the secretion of norepinephrine into the bloodstream or released from nerve endings increases the rate of heart muscle contraction. Any process that modulates the frequency or rate of heart contraction. Any process by which the force of blood traveling through the circulatory system is increased by the chemicals epinephrine and norepinephrine. Any process that activates or increases the frequency or rate of heart contraction. Any process by which the force of blood traveling through the circulatory system is increased. Any process that activates or increases the frequency, rate or extent of heart contraction.
