We report on impedance magnetocardiography studies using high-Tc 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 15 kHz. SQUID measurements are compared to impedance magnetocardiograms recorded at 100 kHz using a copper pickup coil. An electromagnetic finite element model is used to simulate the distribution of ac during the cardiac cycle. [ABSTRACT FROM AUTHOR] |
