It is a clinical problem in cardiology that involves the cardiac conduction system and myocardial electrical activity. It is commonly discussed in acute care (emergency department, ICU) and longitudinal care (outpatient clinics). It is most often identified and characterized using an electrocardiogram (ECG).
