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. In cardiac physiology, isometric contraction is an event occurring in early systole during which the ventricles contract with no corresponding volume change (isometrically). This short-lasting portion of the cardiac cycle takes place while all heart valves are closed. See more In a healthy young adult, blood enters the atria and flows to the ventricles via the opened atrioventricular valves (tricuspid and mitral valves). Atrial contraction rapidly follows, actively pumping about 30% of the returning blood. As See more The word contains the prefix iso-, derived from the Ancient Greek ἴσος (ísos), meaning equal. Therefore, an isovolumetric contraction is one in which the volume of fluid … See more • Isovolumetric Contraction on cvphysiology.com • Isovolumetric Contraction on medical-dictionary.com See more • Isovolumetric relaxation • Cardiac cycle • Blood pressure See more duration in ms
