Abstract
The high frequency to low frequency ratio HF LF derived from analysis of heart period variability is elevated and associated with mortality in severely injured patients monitored in a hospital The purpose of this study was to test the utility of heart period variability measurements as indicators of injury severity in patients prior to definitive medical intervention We tested the hypothesis that survival is associated with low relative HF LF and death is associated with high relative HF LF
