Chronotropic heart rate
Inotropic force of myocardial contractility
Dromotropic conduction velocity through the AV node
Systole contraction of chamber, blood is being
ejected. Pressure rises during systole.
Diastole rest, relaxation of chamber, chamber is
allowed to fill. Pressure falls during
diastole.
Stroke Volume the amount of blood left ventricle pumps
in each beat. (mL/beat)

Cardiac output- (HR) X (Stroke Volume) Avg. healthy adult=
equation 4-8 L/min
Venous return amount of blood flowing into the right
heart from the systemic ciruclation
Blood Pressure- force exerted by the blood against
definition the walls of the arteries as the
ventricles contract and relax
Blood pressure- (cardiac output) X (peripheral
equation resistance) or you could put it
another way: (HR) (Stroke Volume)
(Peripheral Resistance)
