| 摘 要： | 人体心电信号是心血管疾病医学诊断的重要依据,在基础及临床医学上都有重要意义.由于人体心电信号是典型的非平稳信号,仅靠时域波形分析不能较好的反映其特征和探讨本质.本文通过人体心电信号的时频分析,得到了正常和一些病理的心电信号的典型时频图,从一个新的视角较好的反映出了人体心电信号的一些本质性特征,有望成为医学诊断的一种重要判别依据.

| Abstract: | Electrocardiosignal (ECG) is an important evidence base for the diagnoses of cardiovascular diseases as well as for the researches in basic and clinical medicine. Because it presents typical non-steady signals, the wave in time can not reflect the essential characteristic very well. In this article, by analysis in time-frequency domain,we have obtained some typical time-frequency diagrams of normal ECG and abnormal ECG, which reflect the comparatively essential characteristics of the original signal in some aspects and seem likely to become a basis for validating the relevat diagnosis. |
