A method for obtaining the Magneto-ECG (M-ECG) from MCG Data was proposed by our previous research. In present paper, the related error of this method is analyzed by using a single current dipole model in simulation. The aim is to compare the calculated M-ECG with the recorded ECG and provide a simple method to estimate the myocardial current. Our result indicates that the calculated vector electrocardiogram (V-ECG) is available when an equivalent dipole is under the central area of detecting surface. Furthermore, a comparison of the calculated lead-H M-ECG and the synchronously recorded lead-H ECG is shown from 20 subjects.
