The interventricular septum is quite ... WebFunction. The bundle of His is an important part of the electrical conduction system of the heart, as it transmits impulses from the atrioventricular node, located at the anterior-inferior end of the interatrial septum, to the …
WebThe interventricular septum is the only section of the heart exposed to external pressures. As the right ventricle contracts, the pressure of the right ventricle increases and its long and short axis decrease. The net effect is for the interventricular septum to appear relatively hypokinetic when compared to the other walls of the heart. WebThe membranous septum comprises the upper and posterior portion of the IVS, separates the LV outflow tract (LVOT) from the right atrium and RV, and is a common site for …
