Where is the Purkinje network located?

The Purkinje network, which consists of specialized conducting fibers, is located at the bottom of the heart, specifically in the walls of the ventricles. This network is essential for the rapid conduction of electrical impulses from the bundle of His to the myocardial cells of the ventricles, allowing for coordinated contraction and efficient pumping of blood.

Having the Purkinje fibers positioned towards the bottom of the heart enables them to effectively stimulate the ventricular myocardium just before contraction, ensuring that the ventricles contract in a synchronized manner. This anatomical positioning is crucial for maintaining proper cardiac output and overall heart function.
