The first phase is a brief isovolumetric contraction, lasting about 0.05 s and a longer ejection phase of about 0.30 s. The isovolumetric contraction causes left ventricular pressure to rise above atrial pressure, which closes the mitral valve and produces the first heart sound.
The ejection fraction (EF) is an important measurement in determining how well your heart is pumping out blood and in diagnosing and tracking heart failure. A significant proportion of patients with heart failure happen to have a normal ventricular ejection fraction at echocardiography during examination. Previously called diastolic heart failure, it is now referred to as heart failure with normal ejection fraction (HFNEF) or HF with preserved ejection fraction.
