Long QT Syndrome Video

Long QT Syndrome (LQTS) is a disorder of the heart’s electrical activity. It may cause you to develop a sudden, uncontrollable, and dangerous heart rhythm called an arrhythmia in response to exercise or stress.

Arrhythmias also can develop for no known reason in people who have LQTS. Not everyone who has long QT syndrome develops dangerous heart rhythms. However, if one does occur, it may be fatal.

The term “long QT” refers to an abnormal pattern seen on an EKG (electrocardiogram). An EKG is a test that detects and records the heart’s electrical activity. The QT interval, recorded on the EKG, corresponds to the time during which the lower chambers of your heart are triggered to contract and then build the potential to contract again. These chambers are called ventricles.
