Abstract		Introduction: Andersen syndrome is a rare hereditary disease caused by mutation in the KCNJ2 gene. This gene encodes the inward rectifier potassium channel 2 on the sarcolema of the heart and skeletal muscle cells. Disease is inherited in autosomal dominant manner. More then 50% of cases are caused by de-novo mutations. Andersen syndrome is characterized by a triad of periodic paralysis, dysmorphic features and ventricular arrhythmias due to long QT interval. Case report: During the exercise in fitness club 35 years old man suffered a cardiac arrest. After a successful resuscitation an ECG, Holter electrocardiography, echocardiography, coronary angiography with cardiac catheterisation and electrophysiologic study were performed. No structural heart disease was found. An automatic cardioverter defibrillator was implanted. After two years periodic muscular pains and flaccid muscle weakness developed. Serum potassium concentration during episodes of weakness was reduced. With molecular genetic testing the mutation in the 71. codon (Asp71 His) of the KCNJ2 gene was found that confirmed the diagnosis of Andersen syndrome. Conclusion: In the patients with flaccid muscle weakness or paralysis, who also may have some dysmorphic features, long QT syndrome is possible. With the early proper identification, some dangerous cardiac events could be prevented.
