Key result
Heart rate variability increased during the latter part of baseline and plateau waves of intracranial pressure in TBI patients, followed by a decrease after the event and an increase during recovery.
Why the study?

How does heart rate variability change during plateau waves of intracranial pressure in patients with traumatic brain injury?
Heart rate variability monitoring may help clinicians identify intracranial pressure plateau waves at the bedside in TBI patients, allowing for earlier management.
HRV changes may signal ICP plateau waves in TBI; hypothesis-generating pilot data requiring prospective validation before clinical use.
This study aims to describe heart rate variability during the first episode of plateau waves of intracranial pressure (ICP) in Traumatic Brain Injury (TBI) in order to characterize and identify at bedside this cerebrovascular phenomenon. The general behavior of the heart rate variability (HRV) spectral measures expressed in the medians across patients is concordant with an increased HRV in the latter part of the baseline and plateau wave, followed by a decrease after the event and a new increase during the recovery. In low and high frequency bands the same increase is more marked in the parametric analysis. Interpretation of HRV may help clinicians to better identify the plateau waves and allow earlier management.

Luís et al. (2015) conducted an observational in Traumatic Brain Injury (TBI). Plateau waves of intracranial pressure vs. Baseline and recovery periods was evaluated on Heart rate variability (HRV) spectral measures. Heart rate variability increased during the latter part of baseline and plateau waves of intracranial pressure in TBI patients, followed by a decrease after the event and an increase during recovery.
