The electrocardiogram (ECG) represents an essential diagnostic tool in cardiology and beyond. Classical ECG devices enable the registration of up to 12 leads, whereas modern ECG systems enable additional leads even with a reduced number of electrodes. Additionally, "smart" devices even enable patients to record an ECG at home.
Evaluation of a potential additional benefit of using various modern ECG systems for the detection of ECG alterations typical for myocardial ischemia.
Presentation of various signs of ischemia in the ECG according to the latest guidelines. Demonstration of modern ECG systems and their potential advantage in the detection of signs of ischemia in the ECG based on current study results.
Modern ECG systems with vector-based electrocardiography can facilitate and optimize the detection of ischemic ECG alterations. Smart nonvector-based devices for patients are primarily useful for detection of arrhythmias and do not replace the 12-lead ECG for detection of ischemia, even though they can be useful for documentation of temporary ECG alterations also within the ST-segment.
The ECG systems based on vector electrocardiography can improve the detection of ECG alterations typical for ischemia compared to the conventional 12-lead ECG.
心电图（ECG）是心脏病学及其他领域重要的诊断工具。传统心电图设备最多可记录12导联，而现代心电图系统即使电极数量减少也能实现更多导联记录。此外，“智能”设备甚至能让患者在家自行记录心电图。
评估使用各种现代心电图系统检测心肌缺血典型心电图改变的潜在额外益处。
根据最新指南展示心电图中各种缺血迹象。基于当前研究结果展示现代心电图系统及其在检测心电图缺血迹象方面的潜在优势。
基于向量心电图的现代心电图系统有助于促进和优化缺血性心电图改变的检测。面向患者的智能非向量设备主要用于检测心律失常，在检测缺血方面无法替代12导联心电图，尽管它们对于记录ST段内的临时心电图改变也可能有用。
与传统12导联心电图相比，基于向量心电图的心电图系统可改善缺血典型心电图改变的检测。
