It sits at the center of the heart\u2019s electrical \u201cwiring,\u201d between the atria and the ventricles. Its job is to slow and coordinate signals so the heart pumps in an organized sequence. Clinicians commonly reference the AV Node when interpreting ECGs, evaluating palpitations, or treating certain arrhythmias."}
