This Tiny Cluster Controls Your Heartbeat https://tube.blueben.net/videos/watch/db4d8ace-cb39-42d1-b32c-6063a2e09105 This Tiny Cluster Controls Your Heartbeat The AV node is a tiny cluster of specialized cells that controls the timing of the heart’s electrical signals, allowing the chambers to work together efficiently. Its brief delay gives the ventricles time to fill with blood before they contract, maintaining strong and synchronized circulation. When the AV node malfunctions, the heart’s rhythm can become disrupted, making this small structure essential for normal cardiac function.
