Long QT Syndrome (LQTS)

Long QT Syndrome (LQTS) is caused by a problem with the electrical system of your heart, which controls the timing of your heartbeats. It is usually an inherited condition, but can also be acquired due to certain medications, electrolyte imbalances, or other medical conditions.

This can lead to the development of fast, chaotic heartbeats (arrhythmias) that may cause symptoms such as loss of consciousness or sudden death. 

It is important to work with your healthcare provider to develop a management plan that may include lifestyle changes, medications, and/or rarely a heart device such as an implantable cardioverter defibrillator (ICD).

It is also important to educate your family members about LQTS and have them screened for the condition, as it is often hereditary. With appropriate management and lifestyle changes, many people with LQTS can lead healthy and active lives.
