PROBLEM TO BE SOLVED: To provide an atrial fibrillation detection device and an atrial fibrillation detection method capable of accurately determining a state of atrial fibrillation in a simple method.SOLUTION: An atrial fibrillation detection device includes； storage means (114) that stores the number of abnormal pulse waves for each of the measurements of pulse waves performed a plurality of times； maximum value calculation means (108) for calculating the maximum value of the number of abnormal pulse waves； median value calculation means (110) for calculating a median value of the number of abnormal pulse waves； and atrial fibrillation detection means (112) for detecting a state of the atrial fibrillation when the maximum value calculated by the maximum value calculation means is a predetermined threshold or higher and the median value calculated by the median value calculation means is not zero.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】簡易な方法で精度よく心房細動の状態を判定することができる心房細動の検出装置および心房細動の検出方法を提供する。【解決手段】心房細動の検出装置は、複数回行われる脈波の計測の各々について異常な脈波の数を記憶した記憶手段（１１４）と、異常な脈波の数の最大値を算出する最大値算出手段（１０８）と、異常な脈波の数の中央値を算出する中央値算出手段（１１０）と、最大値算出手段により算出された最大値が所定の閾値以上であり、かつ中央値算出手段により算出された中央値が０でない場合に、心房細動の状態を検出する心房細動検出手段（１１２）とを含む。【選択図】図１
