  1. 21. Atrial fibrillation : treatment, associated conditions and quantification of symptoms

    Författare :Niklas Höglund; Steen Jensen; Milos Kesek; Karl Franklin; Juhani Koistinen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; cardioversion; atorvastatin; high-sensitivity C-reactive protein; symptoms; sleep apnea; kardiologi; Cardiology;

    Sammanfattning : Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia. There is a need for new pharmacological treatment strategies since the current antiarrhythmic drugs have a modest efficacy and may have severe side effects. Cardioversion (CV) of AF offers an opportunity to study related conditions in sinus rhythm (SR) and during AF. LÄS MER

  2. 22. Neurohormonal activation, Symptoms and health-related quality of life in patients with atrial fibrillation eligible for radiofrequency ablation

    Författare :Emmanouil Charitakis; Håkan Walfridsson; Urban Alehagen; Jonas Schwieler; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Atrial fibrillation (AF) is the most common cardiac arrhythmia. In order to improve the management of patients with AF, a better understanding of patients’ arrhythmia-related symptoms and health-related quality of life (HRQoL), as well as a finer grasp of the effect of AF initiation and the revolutionary treatment of radiofrequency ablation (RFA) on neurohormonal balance are of great importance.

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

    Författare :Rolf Hörnsten; Urban Wiklund; Staffan Andersson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physiology; Klinisk fysiologi;

    Sammanfattning : 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). LÄS MER

  4. 24. Characterisation of Atrial Electrophysiology with respect to Atrial Fibrillation - A Non-Invasive Approach

    Författare :Fredrik Holmqvist; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Atrial fibrillation; Human; Conduction; Signal; Spectral analysis; P wave morphology; Atrial remodelling; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Atrial fibrillation (AF) is the most common form of cardiac arrhythmia encountered in clinical practice, accounting. Recent findings highlight the need for better characterisation of the arrhythmia in each patient, in order to improve patient treatment. LÄS MER

  5. 25. Computer-based modeling and simulation in the analysis of cardiac arrhythmias and cardiac pacing

    Författare :Hans Åhlfeldt; Linköpings universitet; []
    Nyckelord :arrhythmogenic mechanisms; modulated parasystole; phase response curve; pacemaker follow-up; modeling; simulation; MEDICINE; MEDICIN;

    Sammanfattning : Most systems for ECG analysis deal with QRS classification and arrhythmia detection but do not address the problem of finding the underlying mechanism responsible for the manifest arrhythmia. Although it is possible to distinguish among different arrhythmogenic mechanisms on the cellular level, it is far more difficult in the clinic based on ECG recordings. LÄS MER
