automatic ecg waveform detection 心电波形自动检测
Conclusion the baseline wander is accurately removed and the ECG waveform is better retained., which lays foundation for the following ECG automatic detection.
结论：该方法可以准确地去除基线漂移分量，并保留ecg的波形变化，为后续的ECG自动检测奠定了基础。
The studies include development of generating system of 12-lead synchronous abnormal ECG waveform database, wavelet based QRS complex detection algorism and waveform analysis.
建立了12导联同步心电异常波形数据库生成系统，并在此基础上研究了12导联心电图实时分析与基于小波变换的QRS波自动识别算法。
But the pulse waveform obtained from this method merely has distinctive features such as the QRS complexes in ECG, so the ratio of correct detection of pulse waveform is always low.
由于采用双波长法得到的脉搏波信噪比较低，且脉搏波又不具有明显的特征(例如心电信号中有QRS波群)，因此常用的脉搏波波形识别方法正确检出率不高，经常出现漏检或误检。
