They are a pharmacologic therapy used in cardiology, internal medicine, and perioperative care. They are commonly used to manage heart rhythm, blood pressure, angina, and certain forms of heart failure. They are also used in selected non-cardiac conditions where sympathetic (\u201cfight-or-flight\u201d) signaling is clinically relevant."}
