  2. 11. New Methods for Automated Interpretation of Electrocardiograms and Lung Scintigrams

    Author : Holger Holst; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Decision Support System Clinical ; Image Processing Computer-Assisted ; Radionucleotide Imaging; Pulmonary Embolism; tomography; radiology; Neural Networks Computer ; Electrocardiography; Clinical physics; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : The principal purposes of the studies reported in this thesis were to develop new methods to make computerised decision support systems in medicine both more reliable and fully automated. These aims were pursued in the belief that the solution to these problems will lead to an increased clinical use of such systems resulting in benefit to both patient and physician. READ MORE

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

    Author : Tomas Jernberg; Uppsala universitet; []
    Keywords : Medical sciences; ST-monitoring; electrocardiography; vectorcardiography; myocardial infarction; unstable angina; prognosis; low-molecular-weight heparin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : 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.

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

    Author : Markus Lingman; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
