- The events of the cardiac cycle cause cyclical changes in left ventricular pressure and volume over time. Another way to represent these events is with a pressure-volume loop, as shown below. Drag the labels from the left into the appropriate boxes on the pressure- volume loop to demonstrate your understanding of the cardiac cycle. Aortic valve closure AV valve opening Systolic pressure Isovolumetric relaxation Isovolumetric contraction 120 Diastolic pressure Ventricular filling 80 End-diastolic volume Ventricular ejection 40 AV valve closure End-systolic volume Aortic valve opening 60 120 LV volume (mL) O McGraw-Hill Education Reset LV pressure (mm Hg)Why is it important for medical coding and billing specialists to know about the cardiovascular system in their roles?A 67-year-old-man is in the operating room undergoing a hip replacement.
