   Sammanfattning : The diagnostic potential of beat-to-beat QRS amplitude variability in patients with coronary artery disease (CAD) was evaluated with variance ECG and compared to exercise stress test and myocardial scintigraphy (SPECT). Two high prevalence populations of 199 and 166 patients each were investigated. LÄS MER
