を有して成る心電図モニタ。 Noise for detecting noise input outside the band by having first and second filters inputting the electrocardiogram signal induced by the electrode and amplified, and a band elimination filter for removing the main component of the electrocardiogram signal. a detection circuit; a switching circuit for selecting the electrocardiogram signal passed through the second filter over that of the first filter in response to the noise detection; and displaying the electrocardiogram signal selected by the switching circuit. the first filter has a wide enough pass band to sufficiently pass the electrocardiogram signal components, and the second filter simply detects the QRS wave and ST level of the electrocardiogram signal. An electrocardiogram monitor that has a pass band narrow enough to determine whether or not there is an abnormality in the electrocardiogram.
