The Purkinje network, also known as the cardiac conduction system, is responsible for the electrical conduction that triggers the heart to contract and pump blood. There are several synonyms for the Purkinje network, including the bundle of His, the atrioventricular (AV) node, and the sinoatrial (SA) node. The bundle of His is a group of fibers that arise from the AV node and branch out into the left and right bundle branches, communicating electrical impulses to the ventricles. The SA node acts as the pacemaker of the heart, initiating the electrical impulses that start each heartbeat. Together, these components of the Purkinje network work to ensure the proper functioning of the heart's electrical system.
