1. Autonomic cardiac control in long QT syndrome : clinical studies of arrhythmogenic triggers
Sammanfattning : 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.

2. Quality Control in ECG-based Atrial Fibrillation Screening
Sammanfattning : This thesis comprises an introductory chapter and four papers related to quality control in ECG-based atrial fibrillation (AF) screening. Atrial fibrillation is a cardiac arrhythmia characterized by an irregular rhythm and constitutes a major risk factor for stroke. LÄS MER
3. Catch Atrial Fibrillation, Prevent Stroke : Detection of atrial fibrillation and other arrhythmias with short intermittent ECG
Sammanfattning : Background: Atrial fibrillation (AF) is the most common arrhythmia in the adult population, affecting about 5% of the population over 65 years. Occurrence of AF is an independent risk factor for stroke, and together with other cardiovascular risk factors (CHADS2/CHA2DS2- VASc), the stroke risk increases. LÄS MER
4. Heart rate variability and vascular function in healthy subjects and in patients with insulindependent (Type 1) diabetes mellitus
Sammanfattning : The incidence of atherosclerosis parallels the decreasing function of the autonomic nervous system. Both atherosclerosis and autonomic dysfunction are common in patients with diabetes mellitus. LÄS MER
5. Atrial Fibrillation. Modulation of the atrial fibrillatory frequency. A non-invasive approach
Sammanfattning : Aim: To non-invasively detect and explore the changes in atrial fibrillatory cycle length (i.e. changes in the atrial refractory period) in humans with chronic atrial fibrillation (CAF) following autonomic modulation and pharmacological intervention. LÄS MER
