Long QT syndrome Treatment in Hyderabad


Long QT Syndrome (LQTS) is a disorder of the heart rhythm that can potentially cause a fast and chaotic heartbeat. These fast heartbeats can cause you to faint suddenly. Some people with this disease have seizures. In some severe cases, LQTS can cause sudden death.

Some people are born with a genetic mutation that causes long QT syndrome (congenital long QT syndrome). Long QT syndrome can be caused by certain drugs, mineral imbalances, or medical conditions (acquired long QT syndrome).


The reasons

Risk factors

The following may increase your risk of developing congenital or acquired long QT syndrome or its symptoms:


Appropriate medical treatment and lifestyle changes can help prevent complications from prolonged QT syndrome.

Complications of long QT syndrome are:

Torsades de pointes (“Torsion des pointes”). It is a life-threatening form of ventricular arrhythmia. The two lower chambers (ventricles) of your heart beat quickly and chaotically, giving the waves on an EKG monitor a twisted look. The heart pumps less blood. Lack of blood in the brain causes you to pass out suddenly, often without warning.

If the episode lasts long, fainting can be followed by a full body attack. If the dangerous rhythm doesn’t correct itself, a life-threatening arrhythmia known as ventricular fibrillation ensues.


Congenital long QT syndrome is caused by a genetic mutation. There is no known prevention. However, with proper treatment, you can avoid dangerous heartbeats that can lead to complications from long QT syndrome.

You may be able to prevent the health problems that lead to certain types of acquired long QT syndrome through regular checkups and good communication with your doctor. It is especially important to avoid drugs that can affect your heart rate and make the QT interval longer.
