WebVentricular Systole: Early (Isovolumetric Contraction): During this stage, the atria relax as the atrioventricular (AV) node fires, starting ventricular contraction (systole) (diastole). Both the AV valves and SL valves are closed, preventing blood from leaving the ventricles or flowing back into the atria.

WebIsovolemic contraction of the ventricle happens from when the AV valve closes until when the Aortic and Pulmonary valves open. In other words all the valves are closed.
