Atrioventricular Nodal Reentrant Tachycardia (AVNRT): A type of SVT caused by a dual pathway within the node itself. 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.
Exploring Atrioventricular Node Meaning Through Diagnostic Tests
Diagnostic and Treatment Approaches Medical professionals evaluate the atrioventricular node meaning in clinical settings using electrocardiograms (ECGs) to detect conduction abnormalities. Physiological Role and Electrical Conduction At the core of the atrioventricular node meaning is its role as a gatekeeper in the heart's electrical pathway.
Without this precise delay, the heart would function inefficiently, compromising the systemic circulation of blood. This critical pause allows the atrioventricular valves to open fully and the ventricles to fill with blood before they contract, optimizing the efficiency of each heartbeat.

Conversely, pathways around the node can create accessory circuits, leading to supraventricular tachycardias (SVT), where the heart beats excessively fast. Clinical Significance and Arrhythmias Anatomically, the atrioventricular node is situated in the Koch's triangle, a region within the right atrium.
