PROBLEM TO BE SOLVED: To provide an electrocardiograph that is capable of suppressing missing of electrocardiographic waveform information to be provided to a user even when displaying or printing multiple electrocardiographic waveform components on the same screen or on the same recording sheet after reducing waveforms in some sections.SOLUTION: In a reduced waveform output step, an electrocardiograph displays or prints limb lead waveforms and chest lead waveforms in a prescribed period on the same screen or on the same recording sheet after reducing waveforms in some sections. On the other hand, in an unreduced waveform output step, the electrocardiograph displays or prints the limb lead waveforms and the chest lead waveforms in the prescribed period on the same screen or on the same recording sheet without reducing the waveforms in the some sections.COPYRIGHT: (C)2014,JPO&INPIT【課題】複数の心電波形成分を一部の区間の波形を削減して同一画面に表示又は同一の記録用紙に印刷する場合でも、ユーザに提供する心電波形の情報の欠落を抑制できる心電計を提供すること。【解決手段】削減波形出力ステップでは、所定期間の四肢誘導波形と胸部誘導波形とを、一部の区間の波形を削減して、同一画面に表示又は同一の記録用紙に印刷する。一方、非削減波形出力ステップでは、前記所定期間の四肢誘導波形と胸部誘導波形とを、前記一部の区間の波形を削減せずに、同一画面に表示又は同一の記録用紙に印刷する。【選択図】図4
