Cardiac Conduction System in the Adult Heart

Electrical conduction system of the heart occurs through specially modified cardiac muscle cells.

  • Week 7 (GA) - SA node initially develops in the sinus venosus and then is incorporated into the RA.
  • AV node arises slightly superior to the endocardial cushions.


  • SA node - sinoatrial node located on the anterior border of the opening of the superior vena cava.
  • AV node - atrioventricular node located near the orifice of the coronary sinus in the annular and septal fibres of the right atrium.
  • bundle of His
    • Left bundle branch
    • Right bundle branch
    • moderator band - primary conduction path in to the free wall originating from the right bundle branch.
