AB  - Data from simulations of the anterior myocardial infarction (AMI) and inferior 
      myocardial infarction (IMI) are presented. One infarct located in the anterior 
      section of the left ventricle and a second one in the inferior wall of the left 
      ventricle were modeled. A high-resolution finite element model of a heart and 
      torso was used in this study. Differences in the normal and infarcted fields were 
      computed. Our data suggest that the infarcted region contribution to the total 
      magnetic field can be accounted for by an equivalent current dipole. It might 
      also be possible to detect an infarct from these difference fields constructed 
      for different cases of myocardial infarction. More simulations are needed to 
      determine the relations between infarct sizes and locations and magnetic fields. 
      These relations might then be used to detect various cases of myocardial 
      infarction.
