PURPOSE:To enable the combined observation of the potential changes in the directions of X, Y and Z axes in the body and the immediate and easy understanding of an electrocardiogram on the body surface only with a glance at the indicated surface by not only indicating with color the electrocardiogram potential over the whole region of the body surface, but also adding also a Lissajous's display. CONSTITUTION:In an apparatus composed of a electrocardiogram signal level detecting means 1, level interpolation calculating means 2, memory means 3 and color display control means 4 of a color display device 5, a electrocardiogram signal synthesizing means 6 adds and composes the electrocardiogram signals in predetermined times respectively induced to electrode groups in the directions of X, Y and Z axes in addition and a Lissajous's display control means 7 is so as to composed of display the Lissajous's curves of XY axis, XZ axis and ZY axis according to the composed potential of these axes on the color display device 5. Then, in addition to the color display of electrocardiogram potential over the whole region of body surface, the cubic potential direction in the body under the potential condition of electrocardiogram is displayed, so that high accuracy diagnosis data can easily be obtained only by observing the displayed surface. |
