Analysis of high-frequency QRS components (HF-QRS) increases the diagnostic performance of the standard ECG, though more knowledge is needed before clinical application.
Analysis of high-frequency QRS components may increase the diagnostic performance of standard ECG for conditions like acute myocardial ischemia, though further research is needed before routine clinical use.
HF-QRS may improve ECG ischemia detection; leaves open clinical adoption pending further validation.
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.

Trägårdh et al. (2007) conducted a review in Heart disease. High-frequency QRS components (HF-QRS) vs. Standard 12-lead ECG was evaluated. Analysis of high-frequency QRS components (HF-QRS) increases the diagnostic performance of the standard ECG, though more knowledge is needed before clinical application.
