PROBLEM TO BE SOLVED: To improve the availability of an electrocardiographic report regarding an electrocardiographic data processor, an electrocardiographic data processing method and an electrocardiographic data processing program.SOLUTION: The electrocardiographic data processor 100 processes the measured results of I induction, II induction, III induction, aVR induction, aVL induction, aVF induction, V1 induction, V2 induction, V3 induction, V4 induction, V5 induction and V6 induction obtained by a standard 12 induction method. In the electrocardiographic data processor 100, an operation part 102 and an output apparatus control part 110 constituting a plotting part position and plot a vector electrocardiogram and a scalar electrocardiogram so that the scalar electrocardiogram is disposed around the vector electrocardiogram on the basis of the measured results.COPYRIGHT: (C)2009,JPO&INPIT【課題】心電図レポートの有用性を向上させること。【解決手段】心電図データ処理装置100は、標準12誘導法によって得られる、I誘導、II誘導、III誘導、aVR誘導、aVL誘導、aVF誘導、V1誘導、V2誘導、V3誘導、V4誘導、V5誘導及びV6誘導の測定結果を処理する。この心電図データ処理装置100において、描画部を構成する演算部102及び出力機器制御部110は、この測定結果に基づいて、ベクトル心電図とスカラー心電図とを、前記スカラー心電図が前記ベクトル心電図の周囲に配置されるように位置合わせして描画する。【選択図】図4
