When new technologies are added to the previously existing ones, the latter can be prematurely discarded and judged obsolete not only on the basis of rational scientific facts, but also on irrational trends. Old techniques, like electrocardiography, suffer from diagnostic ambiguities that can be solved by combination with a cardiac imaging technique, like stress echocardiography. ECG monitoring during all forms of stress testing can still offer surprising dividends for a better understanding of the complex physiology of coronary artery disease, a better clinical characterization of patients with microvascular angina, and may serve as an important adjunct marker to cardiac imaging techniques.
当新技术被添加到先前存在的技术中时，后者可能会被过早抛弃，并被判定为过时，这不仅基于合理的科学事实，还基于非理性趋势。像心电图这样的旧技术存在诊断模糊性，而这可以通过与心脏成像技术（如负荷超声心动图）相结合来解决。在所有形式的压力测试期间进行心电图监测，对于更好地理解冠状动脉疾病的复杂生理学、更好地对微血管性心绞痛患者进行临床特征描述，仍然可以带来意想不到的收获，并且可以作为心脏成像技术的重要辅助标志物。
