摘要
目的扩展深化载人航天条件下心电信息的分析方法。方法针对心电信号波形形态间的相似性信息,提出心电相关序列(electrocardio-correlation sequence,ECCS)的分析方法,并对试验数据、MIT-BIH数据库中的数据构建出心电相关序列,进行分析。结果心电相关序列较好地展现了心电信号波形形态相似程度的变化趋势。结论心电相关序列可以在载人航天条件下从一个新的途径研究心肌电活动情况。
Objective To extend the analysis methods of ECG signals in the environment of space fight. Methods The analysis method of ECCS （electrocardio-correlation sequence） was advanced basing on the morphological correlation of sequential ECG signals. ECG data from experiment and MIT-BIH database were analyzed. Results ECCS could describe the changing trend of the correlative degree of sequential ECG signals. Conclusion ECCS provides a new way for studying cardiac electric activity in the condition of manned spaceflight.
