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. WebApr 24, 2014 · D. during isovolumetric contraction.

What happens during ventricular contraction? - KnowledgeBurrow

WebIsovolumetric ventricular contraction occurs between the closing of AV valves and opening of aortic and pulmonary valves, while the ejection phase is longer, lasting for about 0.30 s. The isovolumetric ventricular contraction phase is a short phase lasting for just 0.05 s and making 6% of cardiac cycle duration.
