It is part of cardiac anatomy and physiology within the heart\u2019s conduction system. It is commonly discussed in electrocardiography (ECG), arrhythmias, and atrioventricular (AV) conduction blocks. It is also a key target in electrophysiology (EP) testing and some catheter ablation strategies."}
