Genetic testing for long QT interval
Long QT syndrome is a disorder of the electrical activity of the heart which can lead to a dangerous arrhythmia during excessive physical activity or psychological stress. Long QT interval may be inherited. In addition, certain medications may prolong the QT interval and trigger a dangerous arrhythmia; including in those people with a congenital long QT interval. This dangerous arrhythmia does not appear in all people with a long QT, but if and when it does, it is often fatal.
Why to analyze your DNA for long QT interval?
Long QT interval is a serious condition which is often fatal. If we discover you have increased risk for developing the disease, preventive measures can be taken, to lower the possibility for potentially dangerous and deadly arrhythmia.
Can long QT interval be prevented or treated?
Long QT interval is a condition, where prevention plays extremely important part in disease management. Individuals who were found to suffer from a congenital long QT syndrome due to a minor genetic variation should avoid excess physical activity, professional and extreme sports as well as emotional stress. It is also important for them to avoid certain medications that tend to prolong the QT interval. Of utmost importance is also the prevention and therapy of disease states that can lead to a low level of serum potassium. The prime examples include vomiting and diarrhoea.
