The system utilizing 64 low-transitionerature superconducting quantum interference devices was tested to detect the time-dependent magnetocardiac signals that are spatially distributed over the heart. To achieve efficient acquisition and analysis, we propose a method to detect two-dimensionally, the T wave propagation of electromagnetic signals of beating hearts. In addition to characterizing the propagating behaviors, the differences between normal hearts and those with coronary artery disease were investigated. © 2008 American Institute of Physics.en-USquantum interference deviceSQUID-MAGNETOMETERsystemGRADIOMETER[SDGs]SDG3journal article10.1063/1.29131582-s2.0-44249127027WOS:000256564200118
