What is the function of the Bundle of His?

Explanation:
The Bundle of His is a key part of the heart’s electrical wiring that carries the impulse from the AV node into the ventricles. It travels through the upper part of the interventricular septum and then splits into the left and right bundle branches, which extend down to the Purkinje fibers. This division and rapid transmission to the Purkinje network ensure the ventricles are activated in a coordinated, timely fashion for synchronized contraction. The other options describe functions of different parts of the conduction system (such as the SA node) or pathological blocking, which are not the normal role of the Bundle of His.
