我们研究人类心电图的工作假设下，波动超出了单心动周期的规则结构的不可预测的属性。在此背景下，我们讨论了使用相空间嵌入方法对这种信号的可能性。特别是，随机或高维分量的特定性质允许我们使用相空间嵌入某些信号处理任务。作为实际应用，我们讨论了噪声滤波，胎儿心电图提取，和临床相关功能的自动检测。本文的主要目的是连接嵌入理论的结果，以前没有在实践中应用，并在理论上尚未得到证明的实际应用。[S1063-651X（98）10911-X]。
We study properties of the human electrocardiogram under the working hypothesis that fluctuations beyond the regular structure of single cardiac cycles an unpredictable. Against this background we discuss the possibility of using the phase space embedding method for this kind of signal. In particular, the specific nature of the stochastic or high-dimensional component allows us to use phase space embeddings for certain signal processing tasks. As practical applications, we discuss noise filtering, fetal ECG extraction, and the automatic detection of clinically relevant features. The main purpose of the paper is to connect results of embedding theory that have not been previously applied in practice, and practical applications that have not yet been justified theoretically.
