    Abstract : Background: Long QT syndrome (LQTS) is an inherited cardiac disease characterized by prolonged cardiac repolarization and an increased risk for life-threatening arrhythmias. These arrhythmias are typically triggered by adrenergic stimuli, such as physical activity and intense emotions, implicating that the sympathetic part of the autonomic nervous system (ANS) is involved in arrhythmogenesis.

    Abstract : Background: We aimed to increase the knowledge regarding the familial arrhythmogenic disorder Long QT Syndrome (LQTS) and its recessive variant Jervell and Lange-Nielsen Syndrome (JLNS) in Sweden, including prevalences and clinical phenotypes. A specific focus was directed towards two KCNQ1 mutations –p.Y111C and p. READ MORE

  5. 3. Cardiac arrhythmias and heart rate variability in familial amyloidotic polyneuropathy : A clinical study before and after liver transplantation

    Abstract : Familial amyloidotic polyneuropathy (FAP), found in the northernmost counties in Sweden, is a rare, lethal and inherited amyloidosis. The disease is caused by mutated transthyretin (TTR). The mutation is characterized by an exchange of valine for methionine at position 30 (ATTRVal30Met). READ MORE
