    Sammanfattning : Introduction. Multiple clinical methods for detecting myocardial ischemia are utilised in the hospital setting each day, but there is uncertainty about their diagnostic accuracy. LÄS MER

  2. 2. ST-elevation myocardial infarction studies of outcome in relation to fibrinolysis and ischemia monitoring with on-line vectorcardiography

    Detta är en avhandling från Umeå : Folkhälsa och klinisk medicin

    Författare :Johan Nilsson; Umeå universitet.; [2006]
    Nyckelord :Medicine; Myocardial infarction; vectorcardiography; fibrinolysis; reperfusion; Medicin; kardiologi; Cardiology;

    Sammanfattning : The treatment of acute myocardial infarction (AMI) has undergone a tremendous development during the last decades, and the most important factor is probably the introduction of reperfusion therapy aimed at preventing or limiting the myocardial injury.It is of vital importance that patients with AMI are adequately monitored regarding the development of ECG changes during and after treatment to identify successful or failed reperfusion and to detect episodes of recurrent ischemia.

  3. 3. Multi-lead ST-monitoring in the early assessment of patients with suspected or confirmed unstable coronary artery disease

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : This study evaluated the use of multi-lead ST-monitoring in the early assessment of patients with suspected or confirmed unstable coronary artery disease (UCAD).At continuous 12-lead ECG (c12ECG), the definition of an ischemic episode as a transient ST-deviation ¡Ý0 for at least 1 minute resulted in a good observer agreement (kappa=0.

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    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

  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
