Purkinje fibers are specialized conducting fibers located in which part of the heart?

Purkinje fibers are the terminal part of the heart’s conduction system and are specialized to rapidly spread impulses through the ventricles so the ventricles contract in a coordinated, synchronized way. They form a subendocardial network located in the inner walls of the ventricles, including parts of the interventricular septum. This placement ensures fast, uniform activation of the ventricular myocardium after the impulse travels from the AV node via the bundle of His. They are not located in the atria, and while the AV node region is part of the conduction system, Purkinje fibers themselves reside in the ventricles, making the ventricles the correct location.
