Explanation:
Detailed explanation-1: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection.
Detailed explanation-2: -Atrial systole also happens because of atrial depolarization. The P wave deflection shows this in the ECG. The word ‘systole’ means a contraction in this process. As the atrial muscles contract, the pressure in the atria and blood vessels increases.
Detailed explanation-3: -Atrial systole refers to the phase of the cardiac cycle. During atrial systole the left and right atria contract at the same time and push blood into the left and right ventricle, respectively.
