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.
