PROBLEM TO BE SOLVED: To provide equipment which can analyze atrial fibrillation from a signal whose RR interval can be measured, such as a pulse wave signal and a waveform signal of an electrocardiogram, even when the signal includes an effect of body motion noise.SOLUTION: Atrial fibrillation analysis equipment includes: a detection waveform signal storing region 121 acting as an obtaining unit for obtaining a detection waveform signal representing a result of detection of an electrocardiographic or pulse wave an RR interval calculation unit 112 which, on the basis of the spectrum of each unit period obtained by frequency analysis performed on the obtained detection waveform signal for each unit period which is longer than 4 seconds but shorter than 16 seconds, calculates a parameter corresponding to an average RR interval in each unit period a power calculation unit 113 for calculating the power in a predetermined frequency band in the RR waveform signal representing temporal change of the average RR interval calculated by the RR interval calculation unit and an analyzing unit 114 which determines whether or not the power satisfies a specific condition, and based on the result of the determination, outputs information representing presence or absence of atrial fibrillation.COPYRIGHT: (C)2014,JPO&INPIT【課題】脈波信号および心電図の波形信号などのRR間隔が計測可能な信号において体動ノイズの影響が含まれていても、その信号から心房細動を解析することのできる装置を提供する。【解決手段】心房細動解析装置は、心電または脈波の検出結果を示す検出波形信号を取得する取得部としての検出波形信号記憶領域121と、前記取得された検出波形信号に対して4秒より長く16秒以下の単位期間毎に行われる周波数解析により得られる各単位期間のスペクトルに基づいて、単位期間毎に当該単位期間の平均RR間隔に相当するパラメーターを算出するRR間隔算出部112と、前記RR間隔算出部により算出された平均RR間隔の時間変化を示すRR波形信号における予め決められた周波数帯域のパワーを算出するパワー算出部113と、前記パワーが特定の条件を満たすか否かを判定し、該判定結果から心房細動の有無を示す情報を出力する解析部114とを有する。【選択図】図3
