Abstract
Introduction In patients with suspected coronary artery disease (CAD), stress testing is a standard clinical diagnostic procedure. For instance, changes in the electrocardiogram (ECG) are used as a marker for myocardial ischemia. The use of body surface potential mapping (BSPM) has also been investigated in CAD both at rest and under conditions of dynamic stress [1,2]. The latter have demonstrated that patients with single and multiple vessels disease show changes in particular during repolarization [3]. BSPM has also been performed in conjunction with magnetic field mapping (MFM) in healthy subjects at rest [4] and under stress [5,6]. These studies showed a large degree of correspondence between the electric and magnetic fields whereby differences during ST and T wave intervals have been noted. Some work has been done on MFM in patients with CAD without myocardial infarction (MI) at rest and stress demonstrating differences between spatial as well as temporal aspects of the magnetic
