An electrocardiograph and an electrocardiographic waveform display method for specifying the position of an abnormal waveform in the overall electrocardiographic waveform and displaying the specified abnormal waveform are disclosed. The overall waveform based on the electrocardiographic waveform acquired by measurement is compressed to an area EA, so that the waveform of a portion ( 30 D) specified as an abnormality in the overall waveform is displayed in enlarged form identifiably with the abnormal waveform in the area EB of the same screen. In the overall waveform of the area EA, the position of the waveform of the portion ( 30 D) in the area EB simultaneously displayed is designated. In the case where a plurality of partial waveforms containing an abnormal waveform exist in the overall waveform, the overall waveform can be moved along the arrow AL or AR, so that the waveform (abnormal waveform) of the portion ( 30 D) displayed in enlarged form in the area EB can be sequentially switched to the waveform of the portion ( 30 D) at a position in the direction of movement. |
