A method and an apparatus for monitoring a heartbeat signal are provided based on wavelet transform technique. The method for monitoring the heartbeat signal includes: receiving the heartbeat signal, acquiring a characteristic wave from the heartbeat signal performing time-frequency transform to the acquired characteristic wave, so as to extract a first component within a frequency band which is to be tested from the characteristic wave calculating a ratio between a root-mean-square (RMS) value of the first component and a RMS value of the characteristic wave to obtain an evaluation parameter and determining whether the heartbeat signal is an abnormal heartbeat signal according to the evaluation parameter.一種基於小波轉換技術之心跳訊號檢測方法與檢測裝置。心跳訊號檢測方法包括接收心跳訊號;截取心跳訊號中的特徵波;對所截取的特徵波進行時頻轉換以抽取特徵波中具有待檢測頻段的第一成分;計算第一成分的均方根值與特徵波的均方根值的比值以取得評估參數;以及依據評估參數,判斷心跳訊號是否為異常心跳訊號。S210~S250‧‧‧心跳訊號檢測方法的步驟
