Precordium The portion of the body over the heart and lower chest
Stroke Volume (SV) The amount of blood pumped out of a ventricle during one contraction
Cardiac Output (CO) The amount of blood pumped out of a ventricle in one minute
P Wave Atrial Depolarization - conduction of the impulse throughout the atria
QRS Complex Ventricular Depolarization - conduction of the impulse throughout the ventricles
T Wave Ventricular Repolarization - ventricles return to resting state
Preload End-diastolic stretch of heart muscle fiber. Approximately equal to the end-diastolic volume or pressure
Afterload The forces that impede the flow of blood out of the heart. Composed of pressure in peripheral vasculature, compliance of the aorta, and the mass/viscosity of the blood.
Compliance The ease with which the heart muscle relaxes as it fills with blood
Contractility The force with which the left ventricle contraction occurs. It is independent of the effects of preload or afterload
Hemodynamics A study of the forces involved in circulating blood through the body
