PROBLEM TO BE SOLVED: To eliminate the need for measuring the position of carcass and hart using a special means by measuring the position of hart from the pattern of magnetocardiography. SOLUTION: A magnetocardiography measuring apparatus for measuring the position of hart and correcting the movement of carcass in magnetocardiographic measurement comprises means (11, 12a, 12b) for measuring a magnetic field or a potential incident to electrical action of hart on the outside or surface of body, and means (12-14) for analyzing electrophysiologic phenomenon in the hart by applying an analytical method requiring feature quantities representing the position, orientation and shape of the hart. The magnetocardiography measuring apparatus further comprises means 15 for measuring a signal indicative of respiration of a subject, and means (12a, 12b) for estimating the feature quantities assuming that they are varied according to a specified function depending on the respiration signal. An additive averaging method allowing movement of carcass of the subject by correcting movement of carcass, or continuous measuring method of carcass position is also provided. |
