Exercise magnetocardiography in healthy subjects and single vessel coronary artery disease patients

摘要

Exercise induced ischemia was detected using a novel method for calculating the orientation of magnetic field at ST-segment and T-wave. Magnetocardio-graphic mapping was performed during supine physical exercise testing in 35 subjects including 23 patients with single vessel coronary artery disease. In 12 healthy controls exercise was found to induce a negative change in magnetic field at the ST-segment and T-wave. This prevented the use of similar amplitude parameters as in electrocardiography for the separation of patients and controls.
