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.
In particular, the QT varies with the heart rate. It shortens as the rate increases and lengthens as the rate decreases. Therefore, there is a range of normal or healthy QT intervals. In contrast, the long QT heart often recharges sluggishly or inefficiently as evidenced by a prolonged QT interval on the ECG.he QTc is the value that doctors generally use when assessing for LQTS. In this diagram, since the heart rate (RR) is the same for both examples but the QT interval is longer in the lower panel, the QTc is longer in the lower panel example.
