PROBLEM TO BE SOLVED: To solve such a problem that, in an electrocardiogram information display method for displaying standard 12-lead electrocardiogram waveforms, 6 lead electrocardiogram waveforms as coronal plane lead electrocardiograms and 6 lead electrocardiogram waveforms as thoracic horizontal lead electrocardiograms are displayed, however, it is not easy to highly accurately acquire, by a visual observation of an electrocardiogram, an angle of a maximum QRS vector in the coronal plane and the thoracic horizontal plane, a position of an ischemic part of the heart muscle, and the like.SOLUTION: When a voltage at a same time point with respect to each electrocardiogram waveform on each plane of the coronal plane and the thoracic horizontal plane, is displayed on an axis where an angle of a lead axis of the electrocardiogram waveform and an angle of each axis radially disposed from a center of a graph match, and a radar graph having the radial axes is displayed, it becomes easy to understand a relation between the electrocardiogram voltages and the angles of the lead axes. Further, when an interpolation is performed in the angle direction of each lead axis to increase electrocardiogram waveforms and a radar graph is displayed, the smoothly changing radar graph is provided, so that an operator can highly accurately read the angle of the maximum QRS vector of the heart, the position of the ischemic part of the heart muscle, and the like. |
