Abstract
Description
Claims (1)
- 【特許請求の範囲】 1.高域または帯域フィルタ(2)を用いて心電図(EKG)信号から基線変動 を除去する方法において、 前記心電図(EKG)信号からその都度そのときの心拍数を求めかつそれに依存 して前記フィルタ(2)の下限遮断周波数を、心拍数が増加する場合下限遮断周 波数が高められかつ心拍数が低下する場合下限遮断周波数が低減されるように、 変化することを特徴とする心電図から輪郭変動を除去する方法。 2.心拍数を求めるために、心電図(EKG)信号を遮断分析する請求項1記載 の方法。 3.心拍数を求めるために、心電図(EKG)におけるQRS信号の発生を検出 しかつその都度順次検出されたQRS信号の時間間隔から逆数値を形成する請求 項1記載の方法。 4.入力側に心電図(EKG)信号が供給される高域または帯域フィルタ(2) を用いて心電図(EKG)信号から基線変動を除去するための装置において、 前記帯域フィルタ(2)の下限遮断周波数は変化可能であり、かつ前記フィルタ (2)の入力側は、前記心電図信号から心拍数を求めるための装置(4)の入力 側に接続されており、かつ前記装置(4)の出力側は、下限遮断周波数を制御す るために前記フィルタ(2)の制御入力側(5)に接続されている ことを特徴とする心電図信号から基線変動を除去する装置。 5.心拍数を求めるための装置(4)は、周波数解析器である請求項4記載の装 置。 6.心拍数を求めるための装置(4)は、QRS検出器(6)と、これに後置接 続された、連続して検出されたQRS信号の時間間隔を測定するための段(7) と、該段に接続されている、前記求められた時間間隔から逆数値を形成するため の逆数値形成器(8)とを有する請求項4記載の装置。
