An ECG peak detector 16 squares an ECG signal to generate a squared ECG signal, and a squared ECG signal is subjected to a differential operation to generate a differential/squared ECG signal. The differential operation section 20 and the zero-cross timing detection section 22 for detecting the...

图2 Waveform Peak detection VI 抽取输入波形的波峰/波谷点示意图 对于一段正常典型的心电波形来说,经该VI处理后的结果,可形象地用图3表示出来。 图3 标准ECG波形经Waveform Peak detection VI 处理的前后对比图 当然,对于实际的ECG信号,不可避免地会存在干扰和漂移,很显然,这不会影响到PQRST各特征点的正确抽取...

it is again imperative/helpful if we look at the test phase and training phase of our P2E-Net model separately. Recall that the testing phase of our P2E-Net model needs to do the peak detection of the input PPG signal only (and not the ECG signal, as ECG needs to be rather synthesize...
