  1. 1. Repolarization studies in the long QT syndrome

    Författare :Pia Dahlberg; Göteborgs universitet; []

    Sammanfattning : ABSTRACT Background: Sudden cardiac death in the young is predominantly caused by inherited cardiac conditions. Long QT syndrome (LQTS) is one of the most common of these disorders. Since risk stratification relies largely upon the heart rate (HR) corrected QT interval (QTc), it is crucial to identify an appropriate method for QT correction. LÄS MER

  3. 2. Adaptation of ventricular repolarization to heart rate change in humans

    Författare :Karl-Jonas Axelsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac memory; hysteresis; long QT syndrome; QT adaptation; vectorcardiography; ventricular repolarization;

    Sammanfattning : Background: Life-threatening cardiac rhythm disturbances and sudden death are common manifestations of heart disease. Disturbances in electrical recovery (ventricular repolarization; VR) are important mechanisms behind ventricular arrhythmias, which often occur in relation to changes in heart rate (HR). LÄS MER

    Sammanfattning : Hypoglycaemia is an acute complication to insulin-treatment in type 1 diabetes mellitus, which affects many physiological parameters, deteriorates the cognitive function, and may lead to death. The aim of this thesis was to study nerve function, cognitive function and cerebral blood flow during and after hypoglycaemia in healthy subjects and to study certain aspects of a fall in blood glucose in patients with type 1 diabetes mellitus.
