Prolonged QT syndrome, also known as long QT syndrome (LQTS), refers to a group of disorders that increase the risk for sudden death due to an abnormal heartbeat. Abnormal heartbeats (cardiac arrhythmias) are a primary cause of sudden death, especially in the young population.
The QT interval lasts just a fraction of a second; it normally lasts about one-third of an entire heartbeat. In people with long QT syndrome, the interval lasts longer than it should because heart muscle cells are having trouble getting ready for the next contraction. A prolonged QT interval does not cause symptoms.
