Isovolumetric contraction starts with the closure of the atrioventricular valves. The ventricle spends more time in diastole than in systole. During the cardiac cycle, the ventricular systole precedes the atrial systole. In the systemic circulation, blood enters the heart through the right atrium.

WebJul 30, 2024 · At the start of atrial systole, the ventricles are normally filled with approximately 70–80 percent of their capacity due to inflow during diastole. Atrial …

WebThe cardiac cycle is a continuous sequence of events that occur in the heart, including both contraction (systole) and relaxation (diastole) of the atria and ventricles. The cycle can be divided into several phases as described below: During this phase, both atria and ventricles are in a relaxed state (diastole). WebJan 17, 2024 · Systole describes contraction, when blood is pumped from the heart into circulation by the ventricles. It can also describe atrial systole, in which blood moves …
