Andersen–Tawil syndrome, also called Andersen syndrome and Long QT syndrome 7 which causes muscle weakness, and abnormalities affecting the electrical system of the heart causing abnormal heart rhythms and a variety of facial and skeletal features. These features often include a very small lower jaw, dental abnormalities, low-set ears, widely spaced eyes, and unusual curving of the fingers or toes. It is a rare genetic disorder, and is inherited in an autosomal dominant pattern.
HOW IS ANDERSEN-TAWIL SYNDROME DIAGNOSED?
A cardiologist diagnoses this by conducting: 1. an ECG 2. physical examination for weakness
HOW IS ANDERSEN-TAWIL SYNDROME TREATED?
Treatment must be worked out individually for each patient, and may require modification from time to time. Taking potassium improves weakness in some patients. In some families, taking oral potassium reduces heart rhythm problems but makes muscle weakness worse.
