Web17 sep. 2024 · The sequential events occuring from the initiation of one heartbeat to the commencement of the next is called as one cardiac cycle. In this cycle, the contraction phase is called systole. The relaxation phase is the diastole. A single heart beat comprises a systole and diastole in both atria and ventricles.. Atrial systole WebThe cardiac cycle. The heart relies on its muscle to contract and relax to pump the blood around the body. The left and right sides of the heart are independent of each other, however, will contract synchronously.. When in a contractile state, this is called systole.When in a relaxed state, this is called diastole.. The cycle can then be divided …
