Abstract
Cross-correlation values representative of cross-correlation of an electrocardiogram pulse with a rectangular pulse window which consists of a negative rectangular pulse, a positive rectangular pulse and a negative rectangular pulse are obtained. An R-wave of the electrocardiogram is detected by a peak of the cross-correlation values is detected. Then a magnetocardiogram in synchronism with the R-wave of the electrocardiogram is detected. Magnetocardiograms corresponding to individual cycles of a magnetocardiogram can be added as required.
