Frequency-domain Analysis of ECG Signals

Tu Chengyuan,Zeng Yanjun,Li Shuxin

Strategic Study of CAE 2002, Volume 4, Issue 12, Pages 66-70

Abstract:

A new simple approach to effectively detect QRS — T complexes in ECG curve is described, so as to easily get the P-wave (when AF does not happen) or the f-wave (when AF happens). By means of signal processing techniques such as the power spectrum function, the auto-correlation function and cross-correlation function, two kinds of ECG signals when AF does or does not happen were successively analyzed, showing the evident differences between them.

Nonlinear Science and Its Medical Applications

Tu Chengyuan,Zeng Yanjun

Strategic Study of CAE 2003, Volume 5, Issue 8, Pages 45-49

Abstract:

The fractal-dimension theory and the Shannom entropy theory of nonlinear science are briefly described, and the methods to apply them to analyze AF's information are developed. The grid-dimension values and the Shannom entropy values of P-wave and those of f-wave are computed. The comparison of the remarkable difference between values of these two kinds of waves is given so as to easily determine whether AF happens or not.
