AV node
noun[ C ]
anatomy specialized(alsoA-V node)uk /eɪˈviː ˌnəʊd/ us /eɪˈviː ˌnoʊd/
abbreviation foratrioventricular node: a structure in the heart that causes it to beat when it receives electrical signals:
When the electrical signal travels from the AV node to the ventricles, it causes those chambers to push blood out into the body.
The AV node fires, causing the ventricles, the heart's lower chambers, to beat.
The A-V node connects to a group of fibres that conduct the electrical signal.
This can slow down or stop a number of arrhythmias that originate above or at the AV node.
The study looked at the long-term effects of pacing following AV node ablation.
