  1. 21. Applications of Vectorcardiography for Diagnosis and Risk Stratification in Subpopulations at Risk for Life-Threatening Arrhythmias

    Författare :Daniel Cortez; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vectorcardiography; atrial depolarization; ventricular depolarization repolarization;

    Sammanfattning : Introduction: Vectorcardiography, or 3-dimensional electrocardiography is a tool which can be used to identify subtle changes in the electrical forces of the heart, and which can be applied to atrial depolarization, ventricular depolarization and ventricular repolarization for prognostic and diagostic purposes. Methods: Kor’s regression-related and quasi orthogonal methods was used to derive vectorcardiographic parameters from the 12-lead electrocardiogram and applied to a cohort of cryptogenic stroke patients to assess atrial fibrillation, hypertrophic cardiomyopathy patients to assess for ventricular arrhythmias, applied with right-precordial directed quasi orthogonal method to arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVC/D) patients for diagnosis, and applied to ventricular repolarization only to patients with genotype-positive/phenotype-negative Long QT2 syndrome (KNCH2 mutation) to assess for cardiac events.

  3. 22. Health-related quality of life in recipients with an implantable cardioverter defibrillator due to life-threatening arrhythmias : a 5 year follow-up

    Författare :Inger Flemme; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; defibrillators implantable; ICD shocks; life-threatening arrhythmia; quality of life; satisfaction; uncertainty; MEDICINE; MEDICIN;

    Sammanfattning : The general aim of this thesis was to describe self-reported health-related quality of life (HRQoL) in recipients with an implantable cardioverter defibrillator (ICD) due to life-threatening arrhythmias over a 5-year period. The design was prospective and longitudinal. LÄS MER

  5. 24. Atrial fibrillation : clinical presentation and management, with special emphasis on magnesium therapy

    Författare :Mats Frick; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :atrial fibrillation; magnesium; arrhythmias; cardioversion; sotalol;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, causing disabling symptoms, risk of thromboembolic events and increased mortality. Some patients with AF are asymptomatic, but to what extent these patients differ from patients with symptoms is unclear. LÄS MER

  7. 25. Atrial fibrillation : clinical presentation and prevention of recurrences

    Författare :Anna Nergårdh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Atrial fibrillation; arrhythmias; beta-blocker; cardioversion; symptoms;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained arrhythmia of clinical importance. AF is known to decrease quality of life and it is related to an increased morbidity and a risk of tromboembolic events. AF may also be asymptomatic, and to what extent patients actually are able to distinguish between sinus rhythm (SR) and AF is unknown. LÄS MER
