Reduction of CPR artifacts in the ventricular fibrillation ECG by coherent line removal
CPR artifacts the ventricular fibrillation ECG coherent line removal
2010/2/25
The localized coherent line removal algorithm reduces CPR-artifacts in VF-ECG, but does not eliminate them. Our SNR-improvements are in the same range as offered by multichannel methods of Rheinberger...

基于小波变换的混合二维ECG数据压缩方法
ECG压缩(Electrocardiogram (ECG) compression) 小波变换(wavelet transform) 等级树集合分裂(set partitioning hierarchical trees (SPIHT)) 矢量量化(vector quantization (VQ)) 有效性(validity)
2008/5/21
提出了一种新的基于小波变换的混合二维心电（electrocardiogram, ECG）数据压缩方法。基于ECG数据的两种相关性，该方法首先将一维ECG信号转化为二维信号序列。然后对二维序列进行了小波变换，并利用改进的编码方法对变换后的系数进行了压缩编码：即先根据不同系数子带的各自特点和系数子带之间的相似性，改进了等级树集合分裂（set partitioning hierarchical tree...
