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.
Ventricular diastole is the time when the two lower chambers of the heart called the ventricles are relaxing to let the blood to flow in.
