  1. 31. Signal Characterization of Atrial Arrhythmias using the Surface ECG

    Författare :Martin Stridh; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; Atrial fibrillation; Atrial arrhythmias; Frequency estimation; Time-frequency analysis; QRST cancellation; ECG;

    Sammanfattning : This doctoral thesis is comprised of five parts which deal with different signal processing problems in ECG-based characterization of atrial arrhythmias. Such characterization requires that the ventricular activity has first been cancelled in the ECG. LÄS MER

  3. 32. Evaluation of New Non-Pharmacological Therapies for Symptomatic Atrial Fibrillation : With Special Emphasis on the Maze Procedure

    Författare :Stefan Lönnerholm; Lennart Bergfeldt; Uppsala universitet; []
    Nyckelord :Medical sciences; Atrial fibrillation; Maze procedure; pacing; quality of life; förmaksflimmer; MEDICIN OCH VÅRD; Maze kirurgi; livskvalitet; MEDICINE; MEDICIN; kardiologi; Cardiology;

    Sammanfattning : Atrial fibrillation is a common disease. With pharmacological therapy most patients with atrial fibrillation have moderate or little symptoms, but a number of patients have severely symptomatic disease. This study evaluates two new non-pharmacological therapies for atrial fibrillation, the Maze procedure and atrial overdrive pacing. LÄS MER

  4. 33. Paroxysmal atrial fibrillation : prognostic implications

    Författare :Leif Friberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis is based on data from the Stockholm Cohort on Atrial Fibrillation (SCAF). This cohort consists of all 2912 patients with atrial fibrillation or flutter who were treated as in or outpatients at South Hospital in Stockholm or at Gustavsberg Primary Care Centre during 2002.

  5. 34. Novel risk factors for atrial fibrillation in an urban population

    Författare :Samuel Adamsson Eryd; Kardiovaskulär forskning - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ceruloplasmin; atrial fibrillation; epidemiology; genetic polymorphisms; intima-media thickness; plasma proteins; red blood cell distribution width; risk factors;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in the general population, and a major cause of morbidity and mortality. Low-grade inflammation, erythrocyte volume variation, and subclinical atherosclerosis have repeatedly been associated with cardiovascular disease, but it remains unclear whether these risk factors are also associated with incident AF.

  7. 35. Blood pressure in atrial fibrillation

    Författare :Joakim Olbers; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Hypertension is a leading risk factor for cardiovascular morbidity and premature death. Prevalence of hypertension in the adult population in Sweden has been estimated to 27%. Atrial fibrillation (AF) is the most prevalent sustained arrhythmia of clinical relevance with an estimated prevalence of at least 2.9% among adults in Sweden. LÄS MER
