  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; Göteborgs universitet; Gothenburg University; []
    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

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

    Författare :Bengt Sandstedt; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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

  3. 3. Left ventricular reconstruction in ischemic heart disease

    Författare :Ulrik Sartipy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  4. 4. Cardioplegia and cardiac function : evaluated by left ventricular pressure-volume relations

    Författare :Anders B. Ericsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; cardioplegia; simultaneous cardioplegia; intermittent warn cardioplegia; cardiac function; pressure-volume loops; conductance catheter; heart rate;

    Sammanfattning : Purpose: This thesis is focused on studies of blood cardioplegia in order to evaluate regimens of myocardial protection during cardiac surgery. To further bring down operative mortality and morbidity, in patients with acutely ischaemic hearts, an optimal peroperative myocardial management is essential. LÄS MER

  5. 5. Cardiac memory studies in two human models

    Författare :Liliane Wecke; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Cardiac memory; repolarization; pacing; WPW ablation;

    Sammanfattning : Background Cardiac memory is a form of electrical remodeling of the ventricles, where the T vector follows ("remembers') a previously altered QRS vector. On the electrocardiogram (ECG), it presents as T-wave inversions. LÄS MER
