摘要：
An electrocardiography signal extraction method includes receiving an electrocardiography signal, performing a time-frequency transformation on the received electrocardiography signal to generate a corresponding scalogram, selecting a pre-defined R-pertinent scale, performing the time-frequency transformation at the selected pre-defined R-pertinent scale to generate a R-pertinent summarized response, obtaining a R peak position, selecting a pre-defined QRS-pertinent scale, performing the time-frequency transformation at the selected pre-defined QRS-pertinent scale, obtaining a Q peak position and a S peak position of the electrocardiography signal by finding relative maximum negative responses before and behind the R peak position respectively, obtaining a QRSon position and a QRSoff position by finding relative minimum second derivatives of the responses before the Q peak position and behind the S peak position, respectively.一種心電圖學訊號擷取方法,包含:接收一心電圖學訊號;對該心電圖學訊號執行一時頻轉換,以產生一對應之訊號量圖;選擇該訊號量圖之關於R波的一既定基準值;對關於R波的該既定基準值執行該時頻轉換,以產生關於R波的一歸納響應;獲得R波峰值位置;選擇該訊號量圖之關於QRS複合波的一既定基準值;對關於QRS複合波的該既定基準值執行該時頻轉換;分別找出在該R波峰值位置之前及之後的相對最大負響應,以獲得該心電圖學訊號的Q波及S波峰值位置;分別找出在該Q波峰值之前及S波峰值之後之相對之最小二次微分響應,以獲得QRSon及QRSoff位置。S0S1S2S3S4S5S6S7S8S9S10S101S102S103
