Lecture # 3 Study Notes: Conduction System of the Heart
The conduction system of the heart controls the electrical impulses that regulate the heartbeat. It consists of specialized cardiac tissues, including the sinoatrial (SA) node, atrioventricular (AV) node, bundle of His, and Purkinje fibers.
ATRIAL DEVELOPMENT AND CONGENITAL DEFECTS
Atrial development is a complex process in embryogenesis where the heart’s upper chambers, the atria, form and differentiate. This process involves the creation of the atrial septum, which divides the atria into the right and left chambers, ensuring proper blood flow and separation of oxygenated and deoxygenated blood. Congenital defects in atrial development can lead to atrial septal defects (ASDs), where the septum does not form correctly, resulting in an abnormal opening between the atria.
Lecture # 2 Study Notes: Atrial Development and Congenital Defects
Atrial development involves the formation and separation of the heart’s upper chambers, the atria, during embryogenesis. This process includes the creation of the atrial septum, which divides the atria into right and left sides, ensuring proper blood flow and oxygenation.
