The Bundle of His is a collection of heart muscle fibers located in the heart's electrical conduction system. It plays a crucial role in transmitting electrical impulses from the atria to the ventricles, ensuring that the heart beats in a coordinated manner. This bundle is part of the larger conduction system, which includes structures like the sinoatrial node and Purkinje fibers. The Bundle of His is divided into two main branches: the right and left bundle branches. These branches extend into the ventricles, allowing for synchronized contraction of the heart muscle. Proper functioning of the Bundle of His is essential for maintaining a normal heart rhythm and overall cardiovascular health.
