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

    Författare :Christina M Holmgren; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

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

    Författare :Jacob Odenstedt; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

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

    Detta är en avhandling från Vimmerby : VTT Grafiska

    Författare :Mats-Erik Nygårds; Linköpings universitet.; Linköpings universitet.; [1983]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  4. 4. 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

    Detta är en avhandling från Göteborg

    Författare :Christer Gottfridsson; Göteborgs universitet.; Gothenburg University.; [2000]
    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

  5. 5. Acute coronary syndromes. The prognostic importance of hypertension, diabetes and vectorcardiographic markers

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Markus Lingman; Göteborgs universitet.; Gothenburg University.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute coronary syndromes; hypertension; diabetes; percutaneous coronary intervention; prognosis; myocardial ischemia; coronary artery disease; electrocardiography; vectorcardiography; arrhythmia; sudden death; electrophysiology;

    Sammanfattning : Research questions: 1 Is hypertension and diabetes associated with the future risk of death, and recurrent manifestations of cardiovascular disease in acute coronary syndromes (ACS)? 2 How does myocardial ischemia affect depolarization and repolarization of the heart during the early phase of an acute myocardial infarction? 3 What is the prognostic value of accepted vectorcardiographic markers in relation to future risk of sudden cardiac death after ACS? Methodology: Papers I, III and IV studied patients with ACS prospectively and consecutively included at the coronary care unit of Sahlgrenska University Hospital. Paper I deals with 2,329 patients who were followed for a median of 8 years. LÄS MER
