The evaluation of ischemia by the tangential magnetocardiogram in a patient underwent coronary artery bypass grafting

: We tried to evaluate myocardial ischemia in a patient who underwent coronary artery bypass grafting by the measurement of tangential magnetocardiogram. For the visualization of ischemia, we introduced isointegral maps during depolarization and repolarization reconstructed from tangential magnetography. We found different patterns in isointegral maps of the IHD patient compared with those in normal subjects. Post operative isointegral maps showed recovery from ischemia as increase of current volume.
