PROBLEM TO BE SOLVED: To provide an electrocardiogram analyzer and its control method capable of accurately acquiring a subjects respiratory information from an electrocardiogram signal.SOLUTION: An electrocardiogram analyzer extracts two or more electromyogram signals showing different direction components of a muscles action potential variation accompanying respiratory movement from a plurality of electrocardiogram signals and generates a respiratory signal on the basis of a combined magnitude signal obtained by combining the plurality of extracted electromyogram signals.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】被検者の呼吸情報を心電図信号から精度良く取得することが可能な心電図解析装置およびその制御方法の提供【解決手段】複数の心電図信号から、呼吸運動に伴う筋肉の活動電位変化の、異なる方向成分を表す筋電図信号を2つ以上抽出する。抽出した複数の筋電図信号を合成して得られる合成マグニチュード信号に基づいて呼吸信号を生成する。【選択図】図4
