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.
本研究旨在描述创伤性脑损伤（TBI）患者颅内压（ICP）首次出现高原波期间的心率变异性，以便在床边对这种脑血管现象进行特征描述和识别。以患者中位数表示的心率变异性（HRV）频谱测量的总体行为与基线和高原波后期HRV增加一致，随后事件后下降，恢复期间再次增加。在低频和高频波段，参数分析中同样的增加更为明显。HRV的解释可能有助于临床医生更好地识别高原波并实现早期管理。
