Long QT Syndrome: Definition, Uses, and Clinical Overview
Long QT Syndrome is a condition in which the heart’s electrical recovery phase is longer than expected. It is identified mainly on an electrocardiogram (ECG) by a prolonged “QT interval.” It can be inherited or acquired from medications, electrolyte changes, or illness. The term is commonly used in cardiology, emergency care, and perioperative medicine to evaluate fainting and arrhythmia risk.
