Long QT Syndrome

Long QT syndrome (LQTS) is an abnormality in the heart's electrical system that may cause very fast and potentially dangerous heart rhythms or arrhythmias called torsade de pointes. These arrhythmias may cause sudden loss of consciousness and in some cases, sudden cardiac death.

Although the exact frequency of LQTS is unknown, it may be as prevalent as one in 5,000 people and may cause 2,000 to 3,000 sudden deaths in children and young adults each year in the United States.

At UCSF Medical Center, a team of experts can help identify signs and symptoms of long QT syndrome, diagnose the disease and find the best treatment plan for patients.
