Rapid Ventricular Ejection When ventricular pressure becomes greater than aortic pressure, the aortic valve opens (left heart).

#Unit 7. System Physiology – Animal

Rapid Ventricular Ejection

Blood is rapidly ejected from the left ventricle into the aorta through aortic valve, driven by the pressure gradient between the left ventricle and the aorta.

atrial filling begins 

left atrial pressure slowly increases as blood is returned to the left heart from the pulmonary circulation.

end of this phase coincides with the end of the ST segment (or the beginning of the T wave) on the ECG and with the end of ventricular contraction.

Reduced Ventricular

Ejection Ventricular pressure falls because the ventricles are no longer contracting.
