It is a conduction-system disorder discussed in cardiac anatomy, physiology, and arrhythmia care. It is commonly identified on an electrocardiogram (ECG) and correlated with symptoms like bradycardia or syncope. It matters in emergency assessment, inpatient cardiology, and long-term pacing decisions."}
