    Phases of Cardiac Cycle
    There are two phases of the cardiac cycle. In the diastole phase, the heart ventricles are relaxed and the heart fills with blood. In the systole phase, the ventricles contract and pump blood out of the heart and to arteries.

    Cardiac Cycle Divided into seven phases (and duration of phases)
    1)Atrial Systole (0.11s – 0.53s)
    2)Isovolumetric Ventricular Contraction (0.05s
    )3)Rapid Ventricular Ejection (0.22-0.27s)
    4)Reduced Ventricular Ejection (0.22-0.27s)
    5)Isovolumetric Ventricular Relaxation (0.08s)
    6) Rapid Ventricular Filling (0.11s)
    7) Reduced Ventricular Filling (0.19s)
