This triangle is defined by the coronary sinus, the septal leaflet of the tricuspid valve, and the tendon of Todaro. The sinoatrial node generates the initial impulse, which travels through the atria causing them to contract.
Atrioventricular Node Meaning Pacemaker Function and Its Critical Role in Heart Rhythm
This synchronization ensures that blood pressure remains stable and that oxygenated blood is delivered effectively to the brain and organs, a testament to the intricate design of human physiology. While small, roughly the size of a pea, its strategic position allows it to effectively receive electrical impulses from the sinoatrial node and transmit them to the ventricles via the bundle of His.
Without this precise delay, the heart would function inefficiently, compromising the systemic circulation of blood. Upon reaching the atrioventricular node, the electrical signal is temporarily delayed for approximately 0.
Atrioventricular Node Meaning Pacemaker Function and Its Role in Heart Rhythm
For tachycardias involving the node, medications or catheter ablation procedures targeting the node pathways are common interventions to restore a normal heart rhythm. Clinical Significance and Arrhythmias Anatomically, the atrioventricular node is situated in the Koch's triangle, a region within the right atrium.
