- The atrium contracts (atrial systole).The tricuspid valve located between the right atrium and ventricle opens for a short time and then shuts. 接下來右心房收縮（心房收縮期），這是位於右心房與右心室之間的三尖瓣會短時間打開然後閉合。
- At the end of diastole, your heart』s atria contract (an event called atrial systole) and pump blood into the ventricles. 當舒張期結束時，心房收縮（稱為「心房收縮期」）將血液壓入心室。
- At the end of diastole, your heart』s atria contract (atrial systole), pumping blood into the ventricles, and then begin to relax. 舒張期一結束，心房就首先開始收縮（心房收縮期）將血液壓入心室，然後開始放鬆。
