It is part of cardiac anatomy and physiology, specifically the cardiac conduction system. Clinically, it is discussed in arrhythmias, atrioventricular block, bundle branch block, and pacing strategies. It is commonly referenced when interpreting the electrocardiogram (ECG) and during electrophysiology (EP) procedures."}
