Jun 6, 2022 · The interventricular septum (IVS) accommodates the ventricular portion of the conduction system and contributes to the mechanical function of both ventricles. Conditions or diseases that affect IVS structure and function (e.g., hypertrophy, defects, other) may lead to ventricular pump failure and/or ventricular arrhythmias with grave consequences.

The septum prevents the impulse from spreading directly to the ventricles without passing through the AV node. There is a critical pause before the AV node depolarizes and transmits the impulse to the atrioventricular bundle (see Figure 3 , step 3).
Oct 30, 2023 · Synonyms: none. The interventricular septum is the longitudinal partition which separates the left and right ventricles of the heart. It is oriented obliquely to the right, lying at around 45 degrees to the sagittal plane. It forms the left and posterior walls of the right ventricle, and the anteromedial wall of the left ventricle.

The septum contains the dense irregular connective tissue of the cardiac skeleton that prevents the impulse from spreading directly to the ventricles without passing through the AV node. There is a critical pause before the AV node activates and transmits the electrical impulse to the atrioventricular bundle (see Figure \(\PageIndex{3}\), step 3).
After a delay at the AV node, the septum becomes activated (0.16 sec). All the ventricular mass is activated by about 0.23 sec. Regulation of Conduction. The conduction of electrical impulses in the heart occurs cell-to-cell and highly depends on the rate of cell depolarization in both nodal and non-nodal cells.
Mar 3, 2023 · The interventricular septum ensures that blood flows properly through the heart. It flows from the right atrium, into the right ventricle through the tricuspid valve, and then to the lungs. It ...
