MCG SIMULATIONS OF MYOCARDIAL INFARCTIONS WITH A REALISTIC HEART-TORSO MODEL

Data from simulations of the anterior myocardial infarction (AMI) and inferior myocardial infarction (IMI) are presented. One infarct locate d in the anterior section of the left ventricle and a second one in th e inferior wall of the left ventricle were modeled. A high-resolution finite element model of a heart and torso was used in this study. Diff erences in the normal and infarcted fields were computed. Our data sug gest that the infarcted region contribution to the total magnetic fiel d can, be accounted for by an equivalent current dipole, It might also be possible to detect an infarct from these difference fields constru cted for different cases of myocardial infarction. More simulations ar e needed to determine the relations between infarct sizes and location s and magnetic fields. These relations might then be used to detect va rious cases of myocardial infarction.
