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...
Robust algorithm for arrhythmia classification in ECG using extreme learning machine
Robust algorithm arrhythmia classification ECG extreme learning machine
2010/2/25
The experimental results of the entire MIT-BIH arrhythmia database demonstrate that the performances of the proposed algorithm are 98.00% in terms of average sensitivity, 97.95% in terms of average sp...
Unrestrained Facile Measurement of Narrow-band ECG and Respiratory Variation in Infants with a Capacitive Sheet-type Sensor
capacitive sensing non-intrusive monitoring capacitive electrode ECG monitoring respiration
2009/8/24
We propose a new method for obtaining narrow-band electrocardiographic potential (ECG) and respiratory variation in infants through their underwear. This method is based on capacitive coupling involvi...
Tremor suppression in ECG
Tremor suppression ECG
2010/2/25
The proposed method for tremor suppression implements the following three procedures. Contaminated ECG signals are subjected to moving averaging (comb filter with linear phase characteristic) with fir...
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...
Reference signal extraction from corrupted ECG using wavelet decomposition for MRI sequence triggering: application to small animals
corrupted ECG wavelet decomposition small animals
2010/2/26
The efficiency of the presented method has been tested on a group of quite representative signals containing: highly contaminated (mean SNR<-5 dB) simulated ECGs that replicate normal and pathological...
Suppression of AC railway power-line interference in ECG signals recorded by public access defibrillators
AC railway power-line ECG signals public access defibrillators
2010/2/26
Public access defibrillators (PADs) are now available for more efficient and rapid treatment of out-of-hospital sudden cardiac arrest. PADs are used normally by untrained people on the streets and in ...
Removal of power-line interference from the ECG: a review of the subtraction procedure
power-line interference the ECG the subtraction procedure
2010/2/26
Modifications of the subtraction procedure have been used in thousands of ECG instruments and computer-aided systems. Other work has extended this procedure to almost all possible cases of sampling ra...
