Atrioventricular Node

The atrioventricular (AV) node is a small cluster of cells in the heart that plays a crucial role in regulating the heartbeat. Located between the atria (upper chambers) and the ventricles (lower chambers), the AV node acts as a gatekeeper, slowing down the electrical signals from the atria before they enter the ventricles. This delay ensures the atria fully contract and pump blood into the ventricles before they contract. The AV node is essential for maintaining a coordinated and efficient heartbeat, helping to prevent potential issues such as arrhythmias.

    The atrioventricular (AV) node is a crucial part of the heart's electrical system, located between the atria (upper chambers) and ventricles (lower chambers). It acts as a gatekeeper, controlling the electrical signals that travel from the atria to the ventricles. This ensures that the heart beats in a coordinated manner, allowing the atria to contract and fill the ventricles with blood before the ventricles pump it out. If the AV node is malfunctioning, it can lead to irregular heartbeats, impacting overall heart function and health.
