To accurately and speedily perform estimation by referring to the distribution of a magnetic field or potential being calculated by referring to the amount of feature for expressing the position of a heart or the like, and the measured value of the magnetic field or potential, and by estimating the amount of feature.
An SQUID flux meter 11 detects a heart magnetic field waveform at several points on a breast surface, and carries out amplification and filtering processing for sending to a computer 12. An image-capturing device 13 captures sectional image data of a region including the heart of a subject for sending to the computer 12 via an image-transferring device 14. A breath- monitoring device 15 measures a breathing state, and sends a breathing signal to the computer 12. An arithmetic processor 12b of the computer 12 has a CPU as a main circuit, reads stimulant arrival time being stored into a storage 12d, an analysis program of activity potential amplitude, and an execution program such as image transfer and analysis result display, successively processing inputted data, and uses a ventricle model for displaying the distribution data of the estimated stimulant arrival time and activity potential amplitude on a display 12e.
