Long QT Syndrome (Inherited Arrhythmias)
The most common form of an inherited arrhythmia is Long QT Syndrome (LQTS). The condition leaves patients at risk for developing a rapid chaotic arrhythmia called Torsades de Pointes.
This condition may lead to fainting spells, or in some patients cardiac arrest and possibly sudden death. LQTS can be inherited and several members in multiple generations of a family can be affected.
Congential LQTS is estimated to affect one in every 5,000 persons in the United States. LQTS also can be caused by common drugs and medications. Multiple gene (DNA) abnormalities have now been implicated in causing several inherited arrhythmia syndromes including LQTS, Brugada syndrome, catechomaminergic ventricular tachycardia, sinus node and conduction defects, atrial fibrillation, Andersen's syndrome, and short QT syndrome.
Diagnosing Your Condition
Treatments
Treatment for inherited arrhythmia syndromes, including LQTS, may involve:
- Pacemakers to control heart rhythm
- Implantable Cardioverter Defibrillators (ICDs) to prevent sudden death
Additional Treatments
- Limiting physical activity
- Taking medications to prevent the development of a chaotic heart rhythm or avoiding other types of medications
