The standard 12-lead electrocardiogram (ECG) is one of the most commonly used methods for diagnosing heart disease. Standard ECG is not always optimal, however, and new ECG methods can provide additional information. Analysis of high-frequency QRS components (HF-QRS) has been shown to increase the diagnostic performance of the ECG. Several investigators have studied HF-QRS in different cardiac conditions, including acute myocardial ischaemia and myocardial infarction, but more knowledge is needed about the characteristics of HF-QRS before clinicians can use it as an adjunct to standard ECG.
标准12导联心电图（ECG）是诊断心脏病最常用的方法之一。然而，标准心电图并不总是最佳的，新的心电图方法可以提供更多信息。高频QRS波群成分（HF-QRS）分析已被证明可提高心电图的诊断效能。几位研究人员已在不同心脏疾病中研究了HF-QRS，包括急性心肌缺血和心肌梗死，但在临床医生能够将其用作标准心电图的辅助手段之前，还需要更多关于HF-QRS特征的知识。
