| 摘 要： | 本文介绍了近似熵（ApEn)和谱熵（SE）两种复杂性测度，研究了在两组静默（采用中国气功和Kundalini瑜珈练习方法）和正常状态下的心率复杂性。观察到两种状态下复杂度有明显差异，但两种状态下复杂性数值的大小关系对取决于不同的个体。研究结果进一步在心率变化的复杂性方面支持了关于在人体心率和自主调节间存在某种关联的看法，并提供了新的定量描述心率不同状态的方式和途径。

| Abstract: | Two complexity measures, approximate entropy (ApEn) and spectral entropy (SE) were introduced and investigated on heart rate (HR) sequences recorded from healthy young adults by Peng C K with specific traditional forms of Chinese Chi and Kundalini Yoga meditation techniques. According to these measurements, distinctions of complexity between pre medication and medication were observed. However, conclusion as to which state is more complex is subject dependent. The results supported the conjecture that meditation does not appear to be only a psychologically and physiologically quiescent (homeostatic) state as conventionally believed, and there are connections in terms of complexity between beat to beat heart rate dynamics and automatic regulation. |
