During isovolumetric ventricular contraction
WebFigure 1.2. Isovolumic contraction - pressure and volume changes . Red line - pressure in the left ventricle, black - the aortic pressure, dark blue - the pressure in the right atrium, light blue - the ventricular volume. 1.3. Electrocardiogram. The depolarization spreads from the atrioventricular node to the septum and the 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
