8Loss of Sodium or Potassium
Sodium and potassium are two important minerals that play an essential role in your cardiovascular activities. They help with controlling blood pressure and transporting blood to other parts of the body. Thus, when your body loses them unexpectedly, it would lead to some heart issues, including long QT syndrome. Some common health conditions that would trigger a deficiency of both components include hyperthyroidism, malnutrition, bulimia, anorexia nervosa, and severe vomiting or diarrhea. [8]
