Long QT Syndrome

Long QT Syndrome is a condition that is characterized by a delay in repolarization of the heart after the initial depolarization and ventricular contraction. The electrical system of the heart normally functions in a pattern that causes the atria (upper chambers) and then ventricles (lower chambers) to contract. This pattern of normal electrical signals produces a normal ECG with Q, R, S, and T waves. In long QT syndrome, the electrical signals are delayed because the electrical system cannot recharge fast enough to carry a signal. This condition increases the risk of a life-threatening arrhythmia known as ventricular tachycardia.
