The isovolumetric contraction causes left ventricular pressure to rise above atrial pressure, which closes the mitral valve and produces the first heart sound.

In cardiac physiology, isometric contraction is an event occurring in early systole during which the ventricles contract with no corresponding volume change.

The ventricular pressure rises considerably without any change in the ventricular blood volume – isovolumic contraction (fig. 1.2). The blood volume in the ...

During ventricular systole, pressure rises in the ventricles, pumping blood into the pulmonary trunk from the right ventricle and into the aorta from the left ...

During the isovolumetric phase of the ventricular systole, the volume of blood in the ventricle remains the same while the ventricle is contracting.
