The atrioventricular (AV) node is a vital component of the heart’s electrical system. It acts as a bridge between the atria and ventricles, allowing electrical signals to pass from one to the other. Without the AV node, the heart would not be able to beat properly.
The AV node is located in the lower right chamber of the heart, between the atria and ventricles. It is made up of specialized cells that are capable of conducting electrical impulses. These impulses travel from the atria to the ventricles, causing them to contract and pump blood.
The AV node is an important part of the heart’s electrical system because it helps to ensure that electrical signals are passed from the atria to the ventricles promptly. If there is a delay in signal conduction, it can lead to serious problems such as arrhythmias (irregular heartbeat).« Back to Glossary Index
