Patent ID: 7123952

Claim:
A magnetocardiographic diagnosis apparatus for atrial flutter and fibrillation, comprising: a magnetic field distribution measurement device ( 1 ) performing a non-contact magnetic field measurement on a subject's chest at a plurality of coordinates to obtain a plurality of time-series magnetic field data corresponding to said plurality of coordinates, and also using said plurality of time-series magnetic field data to generate time-series magnetic field distribution data on said chest; an arithmetic device ( 5 ) using said generated time-series magnetic field distribution data to generate data representative of a three-dimensional, intramyocardial, electrical behavior of said subject; and a display device ( 6 ) using the data generated by said arithmetic device to superimpose together an image representing a stimulation propagation path of said subject extending from a sinoatrial node to a bundle of His-Purkinje fiber network and an image representing an abnormal, intramyocardial, electrical reentry circuit and display said images, thereby capable of three-dimensionally identifying an abnormal, intramyocardial, electrical reentry circuit.
