  2. 1. Detection of myocardial ischemia : clinical and experimental studies with focus on vectorcardiography, heart rate and perioperative conditions

    Author : Sören Häggmark; Ulf Näslund; Michael F Haney; Mårten Rosenqvist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; myocardial ischemia; pacing; vectorcardiography; electrocardiography; heart rate; myocardial lactate; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; kardiologi; Cardiology;

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

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

    Author : Johan Nilsson; Ulf Näslund; Kurt Boman; Kristian Thygesen; Umeå universitet; []
    Keywords : Medicine; Myocardial infarction; vectorcardiography; fibrinolysis; reperfusion; Medicin; kardiologi; Cardiology;

    Abstract : 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.

  5. 3. 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.

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

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

    Abstract : 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). READ MORE

  7. 5. Repolarization studies in the long QT syndrome

    Author : Pia Dahlberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; long QT syndrome; repolarization; hysteresis; vectorcardiography; QT adaptation; ventricular repolarization;

    Abstract : ABSTRACT Background: Sudden cardiac death in the young is predominantly caused by inherited cardiac conditions. Long QT syndrome (LQTS) is one of the most common of these disorders. Since risk stratification relies largely upon the heart rate (HR) corrected QT interval (QTc), it is crucial to identify an appropriate method for QT correction. READ MORE
