The isovolumetric ventricular contraction phase is a short phase lasting for just 0.05 s and making 6% of cardiac cycle duration.

WebVentricular Systole: Early (Isovolumetric Contraction): During this stage, the atria relax as the atrioventricular (AV) node fires, starting ventricular contraction (systole) (diastole).
