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

    Författare :Anna Lundström; Annika Rydberg; Urban Wiklund; Håkan Eliasson; Jacob Tfelt-Hansen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; pediatrics; exercise; Holter; water immersion; arrhythmia; clinical physiology; ECG; heart rate variability; heart rate response; cardiovascular disease; hjärt- och kärlforskning; kardiologi; Cardiology; pediatrik; Pediatrics;

    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. 2. Quality Control in ECG-based Atrial Fibrillation Screening

    Författare :Hesam Halvaei; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECG; Signal Quality; 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. 3. Catch Atrial Fibrillation, Prevent Stroke : Detection of atrial fibrillation and other arrhythmias with short intermittent ECG

    Författare :Tijn Hendrikx; Herbert Sandström; Mårten Rosenqvist; Per Wester; Peter Nilsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; screening; primary prevention; secondary prevention; handheld ECG; Cardiology; kardiologi;

    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. 4. Heart rate variability and vascular function in healthy subjects and in patients with insulindependent (Type 1) diabetes mellitus

    Författare :Kerstin Jensen-Urstad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :atherosclerosis; autonomic nervous system; blood-glucose control; Holter ECG; heart rate variability; insulin-dependent diabetes mellitus; population-study; ultrasound; vascular endothelium.;

    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. 5. Atrial Fibrillation. Modulation of the atrial fibrillatory frequency. A non-invasive approach

    Författare :Carl Meurling; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elektrofysiologi; Förmaksflimmer; arytmi; Cardiovascular system; Kardiovaskulära systemet; non-invasiv;

    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
