what is the purpose of the avn (atrioventricular node)?

1 doctor answer
Dr. Stanley Berger

Modulate impulses: The AV node is electrical tissue that separates the upper from the lower chambers of your heart. On an ECG, it relates to the PR segment. The AV node slows impulses briefly from the top to the lower chambers of the heart and prevents very rapid upper heart beats from causing dangerous fast heart beating of the major lower chambers of the heart. Blockage of AV node (ablation) stops impulses.
