  1. 1. Noninvasive characterization of patients with monomorphic ventricular tachycardia and ventricular fibrillation using the signal-averaged electrocardiogram. A study on late potentials and spectral turbulence in patients with ischemic heart disease and in healthy subjects

    Författare :Christer Gottfridsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal-averaged ECG; ventricular tachycardia; ventricular fibrillation; late potentials; spectral turbulence; bundle branch block;

    Sammanfattning : Many people die suddenly from sustained ventricular tachyarrhythmias caused by ischemic heart disease, and the sudden death may be the first presentation of heart disease. If the patients at risk of ventricular tachyarrhythmia could be identified, some patients may be saved. LÄS MER

  3. 2. Studies on malignant ventricular tachyarrhythmias and their treatment with an implantable defibrillator

    Författare :Bengt Sandstedt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implantable cardioverter defibrillator; ventricular fibrillation; ventricular tachycardia; predischarge test; defibrillation threshold; discrimination; electrogram morphology; aortic stenosis; hypertrophy; noradrenalin;

    Sammanfattning : Aims: To investigate the hemodynamic, metabolic and autonomic effects of ventricular fibrillation per se during maintained circulation. To study the defibrillation threshold (DFT) and efficacy of a new and thinner ICD lead (DSP) compared with the standard lead (C). LÄS MER

  4. 3. 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.

  5. 4. Adaptation of ventricular repolarization to heart rate change in humans

    Författare :Karl-Jonas Axelsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac memory; hysteresis; long QT syndrome; QT adaptation; vectorcardiography; ventricular repolarization;

    Sammanfattning : Background: Life-threatening cardiac rhythm disturbances and sudden death are common manifestations of heart disease. Disturbances in electrical recovery (ventricular repolarization; VR) are important mechanisms behind ventricular arrhythmias, which often occur in relation to changes in heart rate (HR). LÄS MER

  7. 5. Left ventricular reconstruction in ischemic heart disease

    Författare :Ulrik Sartipy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Left ventricular reconstruction; surgical ventricular restoration; heart failure surgery; left ventricular aneurysm; ischemic heart disease; cardiac remodeling; surgery for ventricular tachycardia;

    Sammanfattning : Objectives: [1] To review our experience with left ventricular reconstruction (LVR) regarding safety (early mortality and morbidity) and long-term survival (Study I). [2] To evaluate LVR including surgery for ventricular tachycardia in patients with preoperative spontaneous or inducible ventricular tachycardia (Study II). LÄS MER
