PROBLEM TO BE SOLVED: To provide an electrocardiogram examination apparatus capable of specifying an abnormal region of a heart easily with a less processing quantity than a 3D-map.SOLUTION: Electrocardiograms of a plurality of portions are simultaneously displayed, and are displayed by adding colors according to the frequency component analysis results of individual portions to the internal electrocardiogram diagrams of a plurality of portions. As a result, it is possible to realize an electrocardiogram examination apparatus capable of specifying the abnormal regions of the heart easily.SELECTED DRAWING: Figure 3【課題】３Ｄマップよりも少ない処理量で、心臓の異常部位を容易に特定できる心電図検査装置を提供する。【解決手段】複数箇所の心内心電図を同時に表示すると共に、各箇所の心内心電図に各箇所の周波数成分解析結果に応じた色を付加して表示する表示する。これにより、心臓の異常部位を容易に特定できる心電図検査装置を実現できるようになる。【選択図】図３
