1. Detection of myocardial ischemia : clinical and experimental studies with focus on vectorcardiography, heart rate and perioperative conditions
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. ST-elevation myocardial infarction : studies of outcome in relation to fibrinolysis and ischemia monitoring with on-line vectorcardiography
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. Multi-lead ST-monitoring in the early assessment of patients with suspected or confirmed unstable coronary artery disease
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. Repolarization studies in the long QT syndrome
Sammanfattning : 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. LÄS MER
5. Adaptation of ventricular repolarization to heart rate change in humans
Sammanfattning : 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). LÄS MER
