Key result
Heart period variability (FD-L) was associated with the need for lifesaving interventions (p=0.0004), but its 82% correct classification rate was only 2% higher than the baseline prediction rate.
Why the study?
Does heart period variability provide added value in identifying the need for lifesaving interventions in prehospital trauma patients with normal standard vital signs?
Observational (n=159)
Does heart period variability provide added value in identifying the need for lifesaving interventions in prehospital trauma patients with normal standard vital signs?
Heart period variability has limited clinical utility for predicting the need for lifesaving interventions in prehospital trauma patients with normal vital signs due to high overlap between patient groups.

Rickards et al. (2010) conducted an observational in Prehospital trauma (n=159). Heart period variability (fractal dimension by curve length) was evaluated on Need for lifesaving interventions (LSI) (p=0.0004). Heart period variability (FD-L) was associated with the need for lifesaving interventions (p=0.0004), but its 82% correct classification rate was only 2% higher than the baseline prediction rate.
