The purpose of this study was to illustrate the use of time-series analysis with long-term cardiovascular responding. Analyses of two successive 1000-minute mean blood pressure and heart-rate series in five chronically instrumented dogs showed that the autocorrelation function of the original series appeared highly nonstationary and that differenciation of the data produced a simple autocorrelation pattern which could be successfully modeled with stepwise autoregression. Evidence for reliable individual differences as well as change over sessions is presented and discussed.
本研究的目的是说明时间序列分析在长期心血管反应中的应用。对五只长期植入仪器的狗的两个连续1000分钟平均血压和心率序列进行分析，结果表明原始序列的自相关函数呈现高度非平稳性，对数据进行差分后产生了一种简单的自相关模式，该模式可以通过逐步自回归成功建模。本文给出并讨论了可靠的个体差异以及不同实验阶段变化的证据。
