The normal magnetocardiogram: I Morphology.

This paper presents a morphological study of the real-time magnetocardiogram (MCG) of normal subjects. The MCGs were obtained using a gradiometric measurement technique, and the magnetic field component perpendicular to the frontal plane (z-compenent) was studied. Forty-one healthy men and women were mapped from 51 positions on the chest, and the statistics of the waveforms of the MCG were computed. In 21 of the subjects both the MCG and the ECG were analyzed. The general behaviour of the MCGs is discussed and proposals for the standardization of the measurements are made.
