Emva kokuba ukubetha kwentliziyo kuhambe nge-AV Node, kuyakuhamba kudlule nge-conduction system ye-ventricle.Igama elithi conduction lithetha ubushushu okanye ukuhamba kombane kuloo nto uhamba ngayo. Oku kwenza okokuba ukubetha kwentliziyo kuye kwii-ventricles. Indawo yokuqala ye-conduction system yi-bundle ye-His. Igama elithi His ligama likagwirha u-(Wilhelm His, Jr) ekunguye owayifumanayo. I-Bundle ithetha uthotho lweengcingo eziqumbene ndawonye zaliqela elinye ngokumelana kwazo. Iyakuthi ke i-bundle (iqela lothotho lweengcingo ezihamba zilandela ngokumelana.) zihamba ngokutyhuthya-tyhutyha isihlunu se-ventricle, Yahlulwe yangamasebe ee-bundle amabini, isebe le-bundle yangasekhohlo kunye nesebe le-bundle yandasekunene. ziyakuhamba ngesebe le-bundle yangasekhohlo zisiya kwi-ventricle yangasekunene zize ke zihambe ngesebe lee-bundle yangasekunene lonzihambe ke ziye kufika kwi-ventricle yangasekunene, ukubetha kwentliziyo kuhamba kuye kungena kwizihlunu ze-ventricular nge-Purkinje Fibers. Yiyo ke lento yenza okokuba i-ventricle ifingane kuthso kwenzeke i-ventricular systole.
