It has been shown that electrocardiotopography applied during the exercise test in patients with coronary heart disease makes the test more sensitive without changing its specificity as compared with the ECG in common 12 leads. The depression of the ST segment occurs on the electrocardiotopogram in the areas of the precardial zone, corresponding to an isolated or pair lesion of the definite coronary arteries. Upon the involvement of all the three main arteries of the heart the site of the depression is indefinite, but its degree rises, being maximal in patients with stenosis of the left coronary artery and right coronary artery. In these patients, the displacement of this segment spreads to all the areas of the precardial zone.
业已表明，对冠心病患者进行运动试验时应用心电地形图，与常规12导联心电图相比，该试验在不改变特异性的情况下更具敏感性。ST段压低出现在心前区的心电图部位，对应于特定冠状动脉的孤立或成对病变。当心脏的所有三条主要动脉均受累时，压低部位不明确，但程度会升高，在左冠状动脉和右冠状动脉狭窄的患者中最为明显。在这些患者中，该段的移位会扩展至心前区的所有部位。
