  1. 1. Arrhythmogenic Right Ventricular Cardiomyopathy : Genetic and Electrocardiographic Aspects on Risk of Ventricular Arrhythmia and Diagnosis

    Författare :Anneli Svensson; Cecilia Gunnarsson; Pyotr Platonov; Lars O. Karlsson; Perry M. Elliott; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Introduction: ARVC (Arrhythmogenic Right Ventricular Cardiomyopathy) is a heritable rare disease of the heart muscle, primarily affecting the right ventricle, that may cause arrhythmias and heart failure.Aim: The overall aim of this thesis was to study various aspects of genetic information and electrocardiography (ECG), for their use in diagnosis and risk evaluation in ARVC.

  3. 2. On the causes of ventricular arrhythmia, its treatment and outcome

    Författare :Christina M Holmgren; Göteborgs universitet; []
    Nyckelord :Cardiac arrest; ICD; ventricular arrhythmia;

    Sammanfattning : On the causes of ventricular arrhythmia, its treatment and outcome Christina Holmgren Institute of Medicine Sahlgrenska Academy at University of Gothenburg Göteborg, Sweden ABSTRACT Background: Ventricular arrhythmia is the most common aetiology of sudden cardiac death. Death can sometimes be prevented by the implantation of a defibrillator (ICD). LÄS MER

  4. 3. Porcine myocardial ischemia-reperfusion studies on cardioprotection, ventricular arrhythmia and electrophysiology

    Författare :Jacob Odenstedt; Göteborgs universitet; []
    Nyckelord :porcine; myocardial ischemia; ventricular arrhythmia; sudden cardiac death; electrophysiology; vectorcardiography; endocardial mapping; spinal cord stimulation;

    Sammanfattning : Background: Coronary artery disease is the primary cause of death in adults in the industrialised world and ventricular fibrillation associated with myocardial ischemia is the main cause of sudden cardiac death. Restoration of blood flow and preservation of myocardial integrity throughout ischemia and reperfusion is essential to improve clinical outcome. LÄS MER

  5. 4. 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

  7. 5. Myocardial electromechanical function in long QT syndrome

    Författare :Dafni Charisopoulou; Michael Y. Henein; Annika Rydberg; Anders Jonzon; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; stress-echocardiography; left ventricular filling; mechanical dispersion; diastolic myocardial function; exercise; arrhythmia; electromechanical window; speckle-tracking echocardiography; myocardial relaxation sequence.; kardiologi; Cardiology; cardiovascular disease; hjärt- och kärlforskning;

    Sammanfattning : AIM: The aim of this thesis is to assess, in LQTS and according to genotype, the myocardial electromechanical (EM) function response to exercise, its relation to symptoms and its response to b-blocker therapy. To achieve this aim, we conducted 4 studies with the following specific objectives: i. LÄS MER
