    It should be 0.2s to 0.3s right? (lacking confidence rn)
    Anyways, at 0.2 - 0.3 secs the ventricles contract (i.e when ventricular pressure is highest, higher than atrial pressure)
    After 0.3s the pressure starts to decrease (ventricular diastole, pressure in the aorta and pulmonary artery is higher).
