Abstract/OtherAbstract:
A computational study of a magneto-electrocardiogram (magneto-ECG) and a correlative locus of the total current dipole vector map are presented. Unlike the ordinary electrocardiogram (ECG), the magneto-ECG is the solution to the inverse problem of electrocardiograph), which is calculated with the magnetic field signals recorded at 36 locations of a human heart surface. Using this method we investigated 6-lead magneto-ECG, the correlative locus of the total current dipole vector during a cardiac cycle and the current density distribution map. We find that the magneto-ECG and the correlative locus of the total current dipole vector map reveal not only the properties of P-wave, QRS-wave, T-wave similar to the common ECG, but also additional information about the electrophysiological activity of the heart. We anticipate that the magneto-ECG and the locus of the total current dipole vector map may avail the early diagnosis of cardiac diseases.
