研究人员在躯干外寻找心脏产生的波动磁场。探测器和受试者被安置在高度屏蔽的外壳中。与心电图同步检测到幅度为10-8到10-7高斯的磁信号，证实了以前的报道。心电图胸部图由不同空间位置的磁场与时间的关系组成，显示了一般的QRS和T波结构，如心电图中一样;该结构随空间位置而变化。
A search was made outside the torso for fluctuating magnetic fields produced by the heart. Detector and subject were housed in a highly shielded enclosure. Magnetic signals with amplitudes of 10-8 to 10-7 gauss were detected synchronously with the ecg, confirming previous reports. A magneto-cardiographic chest map, consisting of the magnetic field plotted against time at various spatial positions, shows general QRS and T-wave structure, as in the ecg; this structure varies with spatial position.
