discovered in 1893 by swiss-born cardiologist and anatomist wilhelm his jr., the bundle of his or his bundle is a collection of heart muscle cells specialized for electrical conduction. as part of the electrical conduction system of the heart, it transmits the electrical impulses from the av node (located between the atria and the ventricles) to the point of the apex of the fascicular branches via the bundle branches. the fascicular branches then lead to the purkinje fibers, which provide electrical conduction to the ventricles, causing the cardiac muscle of the ventricles to contract at a paced interval.

specialized cardiomyocytes located in the sinoatrial node are responsible for generating the electrical impulses that control the heart rate. these electrical impulses coordinate contraction throughout the remaining heart muscle via the electrical conduction system of the heart. sinoatrial node activity is modulated, in turn, by nerve fibres of both the sympathetic and parasympathetic nervous systems. these systems act to increase and decrease, respectively, the rate of production of electrical impulses by the sinoatrial node.
