      Myocardial Infarction.

AB  - We present a new approach of integrated maximum current density (IMCD) for the 
      noninvasive detection of myocardial infarction (MI) using magnetocardiography 
      (MCG) data acquired from a superconducting quantum interference device (SQUID) 
      system. In this paper, we investigated the relationship of the maximum current 
      density (MCD) in the current density map and the underlying equivalent current 
      dipole (ECD) based on a novel method of reconstructing the ECD in the extremum 
      circle of the magnetic field map. The performance of IMCD and the integrated ECD 
      (IECD) approaches were also evaluated by using 61-channel MCG data from 39 
      healthy subjects and 102 patients with ST elevation myocardial infarction 
      (STEMI). Statistical analysis of the healthy and STEMI groups demonstrate that 
      the IMCD approach obtains sensitivity and specificity up to 91.2% and 84.6%, 
      somewhat higher than that of IECD, respectively. The results indicate that IMCD 
      provides spatiotemporal information regarding cardiac electrical activity during 
      ventricular repolarization. This approach may be helpful to diagnose MI in clinic 
      application. The physical concept of the approach is also explained in this 
      paper.
