Long QT Syndrome is a disorder of the electrical system in which the heart cells take longer than normal to recover electrically after each heartbeat.
It can be inherited, acquired after taking certain medications, or caused by a combination of heredity and medications. People with LQTS may be susceptible to ventricular fibrillation, which can lead to death. They may need specialist care and an implantable cardiac defibrillator (ICD).
