It sits in the heart\u2019s central \u201cwiring\u201d system between the atria and the ventricles. Clinicians reference it when explaining heart rhythm problems such as heart block or bundle branch block. It is also a target for certain pacing strategies designed to support a more natural pattern of ventricular activation."}
