  1. 11. Computer-based detection of cardiac arrhythmias : methods and systems

    Författare :Mats-Erik Nygårds; Linköpings universitet; []
    Nyckelord :Arrhythmia; monitoring; feature extraction; QRS delineation; power spectrum; ventricular fibrillation; MEDICINE; MEDICIN;

    Sammanfattning : The aim of this study was to develop methods and systems which could improve the accuracy or arrhythmia monitoring and analysis of long-term ECGs and eliminate or reduce the need for continuous visual ECG screening. The detection of arrhythmias was based on an automatic classification of heart beats, using waveform features obtained from a basis signals representation. LÄS MER

  3. 12. Clinical aspects of device-detected arrhythmias

    Författare :Emma Sandgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : INTRODUCTION: Cardiac implantable electronic devices (CIEDs) enable continuous monitoring of the heart rhythm. CIEDs constitute a unique opportunity for detecting arrhythmias, as the duration of cardiac monitoring is of the utmost importance for the detection rate. LÄS MER

  4. 13. Cardiac arrhythmias and heart rate variability in familial amyloidotic polyneuropathy : A clinical study before and after liver transplantation

    Författare :Rolf Hörnsten; Urban Wiklund; Staffan Andersson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physiology; Klinisk fysiologi;

    Sammanfattning : Familial amyloidotic polyneuropathy (FAP), found in the northernmost counties in Sweden, is a rare, lethal and inherited amyloidosis. The disease is caused by mutated transthyretin (TTR). The mutation is characterized by an exchange of valine for methionine at position 30 (ATTRVal30Met). LÄS MER

  5. 14. Myocardial creatine metabolism in experimental infarction and heart failure

    Författare :Malin Lindbom; Göteborgs universitet; []
    Nyckelord :Energy metabolism; Creatine; Congestive heart failure; Myocardial infarction; Ventricular arrhythmias; Cardiac remodeling; apolipoprotein B; Lipid metabolism;

    Sammanfattning : The failing heart is characterized by changes in structure, function and metabolism. All these changes are usually defined as pathologic remodelling. An important part of this negative remodelling process is disturbances in the myocardial energy metabolism. LÄS MER

  7. 15. Catch Atrial Fibrillation, Prevent Stroke : Detection of atrial fibrillation and other arrhythmias with short intermittent ECG

    Författare :Tijn Hendrikx; Herbert Sandström; Mårten Rosenqvist; Per Wester; Peter Nilsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; screening; primary prevention; secondary prevention; handheld ECG; Cardiology; kardiologi;

    Sammanfattning : Background: Atrial fibrillation (AF) is the most common arrhythmia in the adult population, affecting about 5% of the population over 65 years. Occurrence of AF is an independent risk factor for stroke, and together with other cardiovascular risk factors (CHADS2/CHA2DS2- VASc), the stroke risk increases. LÄS MER
