摘要 提出了一种简便有效的、由心电图 (ECG)曲线提取QRS -T复合波的新方法 ,从而获得P波 (当房颤未发生时 )或f波 (当房颤时 ) ;利用功率谱、自相关、互相关等信号处理技术 ,对它进行了处理和分析 ,特别是 ,比较了未房颤时和发生房颤时的相关信息的显著差别。 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.
