Anatomy of the conduction system
... The rapid spread of impulses through the ventricles is mediated by cells of the His-Purkinje system (HPS). The His bundle is located at the crest of the interventricular septum. The AV node terminates in the top of the His bundle which then branches into a left and right bundle branch. The right bun ...
