Conversely when heart rate recovers following bout of exercise or other physiologically stressful event sympathetic activity first reduced and then parasympathetic activation augmented ad full chapterView topic accessShopping cartContact supportTerms policyCookies are used by this site. Because the semilunar valves are open continued contraction of ventricles increases pressure pulmonary artery and aorta. The failing ventricle or depressed by anesthetic drugs is more sensitive to afterload than normal . In contrast systolic pressure increases rapidly even at low ventricular volumes and continues steady rate before reaching maximum of roughly mmHg ml. Pressure in the aorta is to mm Hg and pulmonary artery . The conclusion of ventricular ejection causes pressure in ventricles to fall below those pulmonary artery and aorta
