Risk Factors
Factors that increase the risk of long QT syndrome can be classified into two main categories: inherited and acquired. Inherited long QT syndrome is more common among individuals who have first-degree relatives with the condition. On the other hand, acquired long QT syndrome can be caused by certain medications or imbalances in essential minerals such as magnesium, calcium, or potassium, all of which can disrupt the normal electrical activity of the heart.
Symptoms of Long QT Syndrome
Long QT syndrome is characterized by various symptoms, including fainting, seizures, and sudden death. These symptoms typically manifest during or shortly after physical exertion, moments of excitement or surprise, and during sleep or upon waking up. It is important to note that while some individuals with long QT syndrome may not experience any symptoms, they can start to appear as early as adolescence.
