Abstract:
(EN) A heartbeat detecting device comprises: a time difference value calculation unit (3) that calculates the time difference value for sampling data from an electrocardiogram waveform; a FIFO buffer (4-1) and a FIFO buffer (4-2) for which the time difference value serves as input; a FIFO buffer (4-3) for which the output of the FIFO buffer (4-2) serves as input; a FIFO buffer (4-4) for which the output of the FIFO buffer (4-3) serves as input; a minimum value detection unit (5) that detects the minimum value M from the time difference value stored in the FIFO buffer (4-2) and the time difference value stored in the FIFO buffer (4-4) at each sampling time; and a heartbeat time determination unit (6) that determines that the sampling time of an output value a is a heartrate time when the difference value M−a between the minimum value M and the FIFO buffer (4-1) output value a is equal to or greater than a threshold value.
(FR) L'invention concerne un dispositif de détection des battements cardiaques qui comprend : une unité de calcul de valeur de différence temporelle (3) qui calcule la valeur de différence temporelle pour des données d'échantillonnage à partir d'une forme d'onde d'électrocardiogramme; un tampon FIFO (4-1) et un tampon FIFO (4-2) pour lequel la valeur de différence temporelle sert d'entrée; un tampon FIFO (4-3) pour lequel la sortie du tampon FIFO (4-2) sert d'entrée; un tampon FIFO (4-4) pour lequel la sortie du tampon FIFO (4-3) sert d'entrée; une unité de détection de valeur minimale (5) qui détecte la valeur minimale M à partir de la valeur de différence temporelle stockée dans le tampon FIFO (4-2) et de la valeur de différence temporelle stockée dans le tampon FIFO (4-4) à chaque temps d'échantillonnage; et une unité de détermination de temps de battement cardiaque (6) qui détermine que le temps d'échantillonnage d'une valeur de sortie a est un temps de battement cardiaque lorsque la valeur de la différence M−a entre la valeur minimale M et la valeur de sortie a du tampon FIFO (4-1) est supérieure ou égale à une valeur seuil.
(JA) 心拍検出装置は、心電図波形のサンプリングデータの時間差分値を算出する時間差分値算出部(3)と、時間差分値を入力とするFIFOバッファ(4-1)およびFIFOバッファ(4-2)と、FIFOバッファ(4-2)の出力を入力とするFIFOバッファ(4-3)と、FIFOバッファ(4-3)の出力を入力とするFIFOバッファ(4-4)と、FIFOバッファ(4-2)に格納された時間差分値およびFIFOバッファ(4-4)に格納された時間差分値のうちの最小値Mをサンプリング時刻ごとに検出する最小値検出部(5)と、最小値MとFIFOバッファ(4-1)の出力値aとの差分値M-aが閾値以上のときに、出力値aのサンプリング時刻を心拍時刻とする心拍時刻決定部(6)とを備えている。
