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.
