The prognostic assessment of patients with severe brain damage is based on clinical judgement using coma scales and electrophysiological examinations, in particular electroencephalography and multimodal evoked potentials. The suitability of the parameter heart rate variability (HRV) and the increase of its suitability by Fast-Fourier-Analysis for such an assessment is discussed. It was demonstrated that the spectral analysis is able to exhibit changes in the different spectral fields in dependence on the degree of severity of the cerebral damage. The comparability with other investigations such as electroencephalography and computer tomography is discussed. Drug influences, the influence of controlled ventilation and the dependence of results on the time of investigation are considered.
重度脑损伤患者的预后评估基于使用昏迷量表和电生理检查（尤其是脑电图和多模态诱发电位）的临床判断。本文讨论了心率变异性（HRV）参数在此类评估中的适用性以及通过快速傅里叶分析提高其适用性的情况。结果表明，频谱分析能够根据脑损伤的严重程度显示不同频谱领域的变化。本文还讨论了其与脑电图和计算机断层扫描等其他检查的可比性。同时考虑了药物影响、控制通气的影响以及结果对检查时间的依赖性。
