  1. 1. Clinical evaluation and implications of left atrial remodeling in atrial fibrillation : From silent cerebral lesions and atrial stunning to novel electrocardiographic tools for prediction of arrhythmia outcome

    Författare :Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; left atrial remodeling; recurrence; new-onset; silent cerebral lesions; white matter hyperintensities; cardioversion; pulmonary vein isolation; risk factors; electrocardiographic predictors; P-wave indices; machine learning; predictive models; Covid-19;

    Sammanfattning : Atrial fibrillation (AF) is the most common cardiac arrhythmia. Left atrial (LA) remodeling and reverse remodeling are associated with cerebral involvement and cognitive function (CF) changes. Risk stratification for AF related outcomes is essential in the management of patients with AF. LÄS MER

  3. 2. Antiarrhythmic and arrhythmic effects of an Ikr-blocking class III agent. A clinical and electrocardiographic study of almokalant

    Författare :Birgitta Houltz; Göteborgs universitet; []
    Nyckelord :Almokalant; class III antiarrhythmic agent; potassium channel blocker; atrial fibrillation; sinus rhythm; conversion; electrocardiographic; QT interval prolongation; T wave morphology; prediction; torsades de pointes; proarrhythmia; QT dispersion; ventric;

    Sammanfattning : The interest in class III drugs has increased over the last decades as being potent antiarrhythmic agents in their mode of action by prolongation of repolarization and with no effect on conduction. Class I antiarrhythmic agents have proven effective in conversion of atrial fibrillation (AF), but may cause serious proarrhythmia. LÄS MER

  4. 3. Electrocardiographic predictors of clinical outcome in ST-elevation myocardial infarction

    Författare :Marina Demidova; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Malignant ventricular arrhythmias, particularly ventricular fibrillation (VF), remain an important contributor to mortality in ST-elevation myocardial infarction (STEMI). The size of myocardial injury is one more important factor influencing the prognosis of STEMI patients. LÄS MER

  5. 4. Heart rate variability in patients with stable angina pectoris

    Författare :Inge Björkander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ambulatory electrocardiographic registrations; autonomic nervous system; coronary artery disease; differential index; heart rate variability; prognosis;

    Sammanfattning : The rate and modulation of the heart beat (i.e. heart rate variability; HRV) are controlled by the autonomic nervous system. Cardiac sympathetic activation decreases and parasympathetic increases HRV. LÄS MER

  7. 5. Prognostic Factors in First-Episode Schizophrenia : Five-year Outcome of Symptoms, Function and Obesity

    Författare :Robert Bodén; Johan Sundström; Leif Lindström; Lena Flyckt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; First-episode; psychosis; schizophrenia; community mental health services; remission; functional outcome; biochemistry; obesity; weight-gain; prediction; autonomic balance; electrocardiography; Psychiatry; Psykiatri; Psychiatry; Psykiatri;

    Sammanfattning : Our knowledge of prognostic factors and optimal treatment organisation in schizophrenia is incomplete. The disparity of outcome measures used has been a major obstacle for research. Increasing evidence has shown that schizophrenia is associated with increased cardiovascular mortality, development of obesity and autonomic nervous system imbalance. LÄS MER
