The electrocardiography after work is assumed as an essential diagnostic aid in the evaluation of the chronic ischaemic heart disease. Differences in the diagnostic relevance of the results are related to the test method used. Therefore, comparison with the findings of selective coronary angiography is necessary, though the subject of ECG after work are functional changes, but that of coronary angiography are morphological ones. This study gives the comparison of both methods in 84 patients. In patients with coronary artery construction (greater than 75%) the diagnostic possibilities of ECG after work are limited. With regard to these patients it is pointed out that except of the obstruction of coronary arteries, as it is to be documented by selective coronary angiography, there are several further factors favourising coronary insufficiency, such as diminished perfusion of the peripheral coronary vessels, high levels of catecholamines, metabolic disturbances, diminished oxygen transport capacity or oxygen delivery. This may also explain the relatively low specifity of 60% of the ECG after work in the recognition of obstructive coronary artery disease.
工作后心电图被认为是评估慢性缺血性心脏病的重要诊断辅助手段。结果的诊断相关性差异与所使用的检测方法有关。因此，尽管工作后心电图的研究对象是功能变化，而冠状动脉造影的研究对象是形态学变化，但仍有必要将其与选择性冠状动脉造影的结果进行比较。本研究对84例患者的两种方法进行了比较。在冠状动脉狭窄（大于75%）的患者中，工作后心电图的诊断可能性有限。针对这些患者指出，除了选择性冠状动脉造影所记录的冠状动脉阻塞外，还有几个进一步促进冠状动脉供血不足的因素，如外周冠状动脉血管灌注减少、儿茶酚胺水平升高、代谢紊乱、氧运输能力或氧输送减少。这也可能解释了工作后心电图在识别阻塞性冠状动脉疾病时60%的相对较低特异性。
