We report on impedance magnetocardiography studies using high-superconducting quantum interference device(SQUID)magnetometers in a partially shielded environment. The SQUID detects magnetic-field variations due to impedance changes in the thorax at . SQUID measurements are compared to impedance magnetocardiograms recorded at using a copper pickup coil. An electromagnetic finite element model is used to simulate the distribution of ac during the cardiac cycle.
