Reduced high-frequency QRS components in patients with ischemic heart disease compared to normal subjects
(2004) In Journal of Electrocardiology 37(3). p.157-162- Abstract
- Analysis of high-frequency QRS components (HF-QRS) might provide an additional method when diagnosing various heart diseases, for example ischemic heart disease (HID). This study compares HF-QRS in normal Subjects to those in patients with HID, and also analyzes HF-QRS considering gender and age. A total of 63 normal subjects and 64 patients with IHD were included. Signal-averaged electrocardiograms (ECGs) from the 12 standard leads were analyzed in the frequency interval of 150-250 Hz. The results showed that the summed 12 lead HF-QRS in patients with IHD were significantly lower than in normal subjects (mean summed HF-QRS was 33.5 muV in the HID group, 43.7 muV in normal individuals, P < .0005). HF-QRS were not statistically... (More)

HF-QRS were not statistically associated with gender or age (P = .820 and P = .573, respectively). However, the inter-individual variation of HF-QRS was large in both groups which probably limits the clinical usefulness of the method. (Less)
