  1. 26. Long QT syndrome : studies of diagnostic methods

    Författare :Ulla-Britt Diamant; Steen M Jensen; Annika Rydberg; Thomas Gilljam; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kardiologi; Cardiology;

    Sammanfattning : Background: The Long QT Syndrome (LQTS) is a hereditary heart disease with risk of malignant ventricular arrhythmia and sudden cardiac death. Despite our increased knowledge about genotype and phenotype correlation we still rely on the 12-lead ECG for assessment of the QT interval and the T-wave morphology for diagnosis and risk stratification.

  3. 27. Metabolic aspects of cardiac arrhythmias

    Författare :Sigfus Gizurarson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiologi; Electrofysiologi; Djurexperiment; Metabolism;

    Sammanfattning : Cardiac arrhythmias are an important cause of mortality and morbidity in patients with cardiac diseases. Sudden death due to ventricular tachycardia and fibrillation (VT/VF) in the setting of acute myocardial infarction (AMI) and heart failure (HF) is a frequent cause of premature death. LÄS MER

  4. 28. Detection of paroxysmal atrial fibrillation : with special emphasis on intermittent ECG recording

    Författare :Peter Doliwa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained form of arrhythmia, affecting approximately 3 % of the adult population. AF may be symptomatic or asymptomatic. Asymptomatic paroxysmal atrial fibrillation (PAF) can be troublesome to diagnose, as most devices for arrhythmia detection provide only limited insight into heart rhythm. LÄS MER

  5. 29. Cardiovascular and respiratory effects of air pollution : application of different observational study designs and analysis approaches

    Författare :Niklas Berglind; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The effect of air pollution exposure on human health has been a topic of an increasing volume of research over the past half century. Due to the ubiquitous nature of ambient air pollution exposure and the comparatively weak effects that can be expected, one of the most viable and most utilized avenues of research has been to conduct large scale observational studies.

  7. 30. Physical Activity and Cardiovascular Disease

    Författare :Kasper Andersen; Johan Sundström; Claes Held; Frieder Braunschweig; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; epidemiology; cohort study; heart failure; cardiovascular disease; arrhythmias; atrial fibrillation; bradyarrhythmias; sudden cardiac death; heart failure; stroke; ischemic heart disease; cardiovascular death; maximal exercise capacity; muscle strength; skeletal muscle morphology; Kardiologi; Cardiology; Epidemiology; Epidemiologi;

    Sammanfattning : The aim was to investigate associations of fitness and types and levels of physical activity with subsequent risk of cardiovascular disease.Four large-scale longitudinal cohort studies were used. The exposures were different measures related to physical activity and the outcomes were obtained through linkage to the Swedish In-Patient Register. LÄS MER
