ATRIAL FIBRILLATION DETERMINATION APPARATUS, AND METHOD AND PROGRAM FOR DETERMINATION OF ATRIAL FIBRILLATION

摘要

PROBLEM TO BE SOLVED: To provide an atrial fibrillation determination apparatus which, even if an influence of body motion noises is contained in a signal such as a pulse wave signal and an electrocardiographic waveform signal in which RR intervals are measurable, can determine atrial fibrillation from the signal.;SOLUTION: An atrial fibrillation determination apparatus 100 comprises: an acquisition part for acquiring a detection waveform signal which shows a detection result of electrocardiographic waves or pulse waves; an RR interval calculation part 112 which, on the basis of the spectrum of each frame obtained by frequency analysis of the previously acquired detection waveform signal, calculates a parameter corresponding to the RR interval for each frame to calculate an RR waveform signal which shows the time-dependent change of the parameter; a power calculation part 113 for calculating a time-dependent change of the power in a predetermined frequency band in the RR waveform signal; and a determination part 114 for determining whether or not the calculated power satisfies a specified condition, and outputting the information according to the result of the determination.;COPYRIGHT: (C)2016,JPO&INPIT
