The cardiac cycle looks at all of the things that happen from the beginning of one heartbeat to the beginning of another. Phase 2 of the cardiac cycle is called Isovolumetric Ventricular Contraction. We cover the QRS complex of the EKG, the roles of the atrioventricular and aortic semilunar valves, the pressure and volume changes in the atria and ventricles, and how these all factor into the building up of the pressure needed to send the blood throughout the body.
