Patent ID: 8103335

Claim:
A cardiogram waveform display device for displaying cardiogram waveforms comprising: a waveform data storage portion that stores waveform data which is converted to digital data from cardiogram waveform signals measured with a cardiograph; a first to an n th filtering means, for carrying out low frequency cut-off processing of the waveform data stored in the storage portion, and for acquiring a first to an n th corrected waveform data, each of the filtering means having a different cut-off frequency; selecting means, for recognizing an amount of variation of a base-line for each of a plurality of segments relative to at least any one of the waveform data and the first to the n th corrected waveform data, and for selecting any one of the first to the n th filters in accordance with the amount of variation of the base-line for each of the segments; and display control means for displaying output of the filter selected for each of the segments by the selecting means.
