This study focuses on a 3-D measurement of magnetocardiograms (MCGs) of a subject with myocardial infarction (MI). We carried out the measurements in a prefabricated magnetically shielded room, using a 3-D second-order gradiometer connected to three rf-SQUIDs, which can detect the magnetic field component perpendicular to the chest (Bz) and tangential to the chest (Bx, By). In this study, fast Fourier transform (FFT) was used to compare the frequency characteristics of MCGs of the MI patient with those of patients who had normal MCGs. Results showed that frequencies of less than 1 Hz dominated in MCGs (Bz, Bx) of the MI patient, compared with frequencies of 1 Hz in MCGs of patients who had normal MCGs.
