Hypokalemic Periodic Paralysis, Facial Dysmorphism and Ventricular Arrhythmia (Clinical Triad of Andersen-Tawil Syndrome)

摘要

Andersen-Tawil Syndrome (ATS) is a rare potassium channel disorder, characterized by episodic weakness, ventricular arrhythmias and dysmorphic features (short stature, scoliosis, clinodactyly, hypertelorism, small or prominent low set ears, micrognathia and broad forehead). We report a case of hypokalemic periodic paralysis with dysmorphic facial features and ventricular arrhythmia resembling Andersen-Tawil syndrome.
