As contraction begins both sets of valves are closed, meaning that no blood can escape from the ventricles. Therefore, the start of systole increases the pressure within the ventricles, ready to eject blood into the aorta and pulmonary trunk. The stage of isovolumetric contraction lasts for approximately 50ms,while the … See more The ventriclesare filled with blood in two stages – diastole (heart relaxation) and atrial systole (contraction of the atria). In diastole, both the atria and the ventricles are relaxed. Blood flows from the vena cavaand pulmonary … See more Once the ventricles’ pressure exceeds the pressure in the aorta/pulmonary trunk, the outflow valves(aortic/pulmonary) open, and blood is pumped from the heart into the great arteries. At the end of systole, around 330ms later, … See more At the end of the outflow phase, both sets of valvesare closed once again. The ventricles begin to relax, reducing the pressure in the ventricles so that the atrioventricular valves open. The ventricles then begin to fill with … See more WebDisturbance in ventricular relaxation results in the disruption of pressure conditions in the left ventricle.
