It is a diagnostic tool used in cardiology, emergency medicine, anesthesia, and critical care. It helps assess heart rhythm, conduction, and patterns that can suggest ischemia or chamber strain. It is commonly used in clinics, ambulances, emergency departments, inpatient wards, and operating rooms."}
