Abstract

The direction of the electromotive force vector (EMF vector) of the heart is determined for at least one selected point in the heart cycle, using electrocardiographical data. The direction of the electric current dipole vector (ECD vector) of the heart is determined for at least the same at least one selected point in the heart cycle, using magnetocardiographical data. The angle between the direction of the EMF vector and the ECD vector at the selected point in the heart cycle is then determined, the angle representing a measurement for the myocardial anisotropy of the heart of the examined patient. It has been shown that the angle determined for patients with coronary artery disease (CAD) lies in a completely different angle zone to the angle determined for healthy patients.
