A method of detecting atrial fibrillation is provided. The method includes the following steps: measuring an information of n heartbeats, n is an integer greater than 1 calculating each time interval between every two heartbeats from 0-th to n-th heartbeats so as to obtain an information of n time intervals calculating each differential value between every two time intervals from the first to n-th so as to obtain n-1 differential values summing the n-1 differential values so as to obtain a summation of differential values dividing the summation of the n-1 differential values by amounts of the differential values so as to obtain an averaged information of the differential values and determining whether the averaged information of the differential values is greater than a predetermined threshold value, if so, the atrial fibrillation is determined. An atrial fibrillation detecting apparatus and an atrial fibtillation detecting system adapted to the method are also provided.本發明提出一種心房顫動偵測方法,包括下列步驟:量測n個連續的心跳資訊,n為大於1的正整數;計算第0個心跳資訊到第n個心跳資訊之間每一個心跳資訊的時間差以獲得n個時間差資訊;計算第1個時間差資訊到第n個時間差資訊之間每一個時間差資訊的差以獲得n-1個差異值;加總n-1個差異值以得到總和差異值;將總和差異值除以差異值個數n-1以獲得平均差異值資訊;以及判斷平均差異值資訊是否超過閥值,若判斷為是,則判定為心房顫動。本發明還提出採用上述心房顫動偵測方法的心房顫動偵測裝置及心房顫動系統。101~106‧‧‧步驟
