Evaluation of Patient with Myocardial Infarction Using Isoenergy Contour Maps of Three-Dimensional Magnetocardiograms

摘要：

A SQUID magnetometer system with three-dimensional(3D) second-order gradiometer was used to measure the magnetocardiograms(MCG) for the normal subject and the patient with myocardial infarction (MI). In order to discuss the activities of the heart between the normal subject and the patient with MI, we have presented the isoenergy contour maps to evaluate the spatial energy distribution (SED) of the QRS complex at different scale. Being different from the normal subject, the patient with MI represented different the pattern of the SEO in various frequency band for the ST segment of the QRS complexof Bx, By, and Bz components. It is helpful to evaluate the patient with MI using the isoenergy contour maps of 3-D MCG.
