It acts like a timing and filtering station between the upper and lower chambers of the heart. Clinicians talk about the AV Node when evaluating heart rhythm problems, slow heart rates, and certain types of rapid heartbeats. It is commonly referenced when interpreting an ECG, diagnosing heart block, or planning rhythm treatments."}
