The interventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the heart, from one another. The interventricular septum is directed obliquely backward to the right and curved with the convexity toward the right ventricle ; its margins correspond ...
The bundle of His branches into the left and the right bundle branches, which run along the interventricular septum. The left bundle branch further divides into the left anterior fascicle and the left posterior fascicle. These bundles and fascicles give rise to thin filaments known as Purkinje fibers. These fibers distribute the impulse to the ...
The AV node functions as a critical delay in the conduction system. Without this delay, the atria and ventricles would contract at the same time, and blood wouldn't flow effectively from the atria to the ventricles. The delay in the AV node forms much of the PR segment on the ECG, and part of atrial repolarization can be represented by the PR ...
Interventricular septal end diastolic dimension: IVSd: The thickness of the interventricular septum. 8.3 mm, [20] Range 7 – 11 mm [21] Left ventricular end diastolic posterior wall dimension: LVPWd: The thickness of the posterior left ventricular wall. 8.3 mm, [20] Range 7 – 11 mm [21] Mean left ventricular myocardial thickness: Mean LVMT
Hypertrophic cardiomyopathy (HCM, or HOCM when obstructive) is a condition in which muscle tissues of the heart become thickened without an obvious cause. [8] The parts of the heart most commonly affected are the interventricular septum and the ventricles. [10]

There are two branches of the bundle of His: the left bundle branch and the right bundle branch, both of which are located along the interventricular septum. The left bundle branch further divides into the left anterior fascicle and the left posterior fascicle. These structures lead to a network of thin filaments known as Purkinje fibers.
