  1. 1. Electrocardiographic Imaging of Myocardial Ischemia, Infarction and Scar: Correlation with SPECT, MRI and Arrhythmias

    Författare :David G Strauss; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Imaging; Arrhythmias; Ischemia; Infarction; Cardiomyopathy; SPECT; MRI;

    Sammanfattning : This thesis focuses on the development and testing of electrocardiographic (ECG) methods to diagnose and characterize myocardial ischemia, infarction and fibrosis (scar). The goal is to provide improved decision support to physicians regarding the optimal selection of patients for two costly, invasive therapies – percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (MI) and implantable cardioverter defibrillators (ICDs) for patients with heart failure and reduced left ventricular ejection fraction (LVEF).

  3. 2. Cryoablation of cardiac arrhythmias

    Författare :Hamid Bastani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis evaluates the safety and efficacy of cryoablation in supraventricular tachyarrhythmias. In Study I, the acute and long-term outcome of cryoablation therapy of typical atrioventricular nodal reentrant tachycardia (AVNRT) was studied in a large series of patients (n=312). LÄS MER

  4. 3. 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

  5. 4. Environmental exposures and cardiac arrhythmias

    Författare :Marcus Dahlquist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiac arrhythmias lead to substantial mortality and morbidity world-wide. The most severe form of cardiac arrhythmia, cardiac arrest, is one of the leading causes of death in Europe and North America. LÄS MER

  7. 5. Assessing Symptom Burden and Health-Related Quality of Life in patients living with arrhythmia and ASTA : Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia

    Författare :Ulla Walfridsson; Anna Strömberg; Kristofer Årestedt; Nils Edvardsson; Linköpings universitet; []
    Nyckelord :Arrhythmias; Symptom burden; Health-Related Quality of Life; Patient-reported outcomes; Validation; Disease-specific questionnaire;

    Sammanfattning : Background: Health-Related Quality of Life (HRQOL) can be negatively affected in patients living with arrhythmias and many patients experience a pronounced symptom burden. The arrhythmia can cause both uncertainty and limitations, including interference with work, reluctance to perform and plan for leisure activities and leading to self-imposed restrictions in daily life situations.
