During isovolumetric ventricular contraction

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