【摘要】 本文介绍了一种基于傅立叶变换的高频心电逐搏变异性特征分析方法,利用模板匹配方法提取心电信号的阵列组,分别计算对应的心电信号功率谱阵列组,并提出了以40～250Hz内的心电信号成分为对象计算每个心搏的能量中心位置和谱能量之和作为评价逐搏变异性的指标,为进一步研究高频心电信号逐搏变异的临床意义提供新方法。更多还原

【Abstract】 this paper introduce a method of beat to beat variability of frequency contents in the high frequency electrocardiogram using fourier transforms,first by applying a method of matched alignment to abstract electrocardio signal array,and then by computing power spectrums array of these ECG.It was presented that energy center and summation of ECG components power spectrums in 40～250Hz will been regard as parameters of evaluation for beat to beat variability of ECG,it will provide a new manner for doing further research on clinical applications of high frequency ECG.更多还原
