血压(BP)的特征是持续波动，包括持续几秒钟的快速变化，以及较慢和较长时间的变化，时间常数为几分钟或几小时。现在可以通过多种数学方法在时间或频域(频谱分析)中评估这些不同分量对总体血压变化的相对贡献。由于血压变异性的复杂性，只有通过分析连续的、逐拍的血压记录才能获得准确和详细的血压变异性评估。然而，一些信息也可以从对不连续的血压轨迹的分析中获得，例如在临床环境中通常进行的那些。这就要求既要注意记录的质量，又要注意选择适当的分析方法，以处理要处理的测量的不连续性质及其固有的低采样频率。(C)2003年，里平科特·威廉姆斯·威尔金斯。
Blood pressure (BP) is characterized by continuous fluctuations, including fast changes lasting only a few seconds as well as slower and more prolonged variations, with a time constant of minutes or hours. Assessing the relative contribution of these different components to overall blood pressure variance is now possible through a number of mathematical approaches, either in the time or in the frequency domain (spectral analysis). Due to its complex nature, a precise and detailed assessment of blood pressure variability can be obtained only from the analysis of continuous, beat-by-beat, blood pressure recordings. Some information, however, can also be derived from analysis of discontinuous blood pressure tracings, such as those commonly performed in a clinical setting. This would require that attention is paid both to the quality of the recordings and to the selection of suitable analysis methods that should cope with the discontinuous nature of the measurements to be processed and to their intrinsic low sampling frequency.
