Abstract EN
Motion artifacts and myoelectrical noise are common issues complicating the collection and processing of dynamic electrocardiogram (ECG) signals.
Recent signal quality studies have utilized a binary classification metric in which ECG samples are determined to either be clean or noisy.
However, the clinical use of dynamic ECGs requires specific noise level classification for varying applications.
Conventional signal processing methods, including waveform discrimination, are limited in their ability to remove motion artifacts and myoelectrical noise from dynamic ECGs.
As such, a novel cascaded convolutional neural network (CNN) is proposed and demonstrated for application to the five-classification problem (low interference, mild motion artifacts, mild myoelectrical noise, severe motion artifacts, and severe myoelectrical noise).
Specifically, this study finally categorizes dynamic ECG signals into three levels (low, mild, and severe) using the proposed CNN to meet clinical requirements.
The network includes two components, the first of which was used to distinguish signal interference types, while the second was used to distinguish signal interference levels.
This model does not require feature engineering, includes powerful nonlinear mapping capabilities, and is robust to varying noise types.
Experimental data are composed of private dataset and public dataset, which were acquired from 90,000 four-second dynamic ECG signals and MIT-BIH Arrhythmia database, respectively.
Experimental results produced an overall recognition rate of 92.7% on private dataset and 91.8% on public dataset.
These results suggest the proposed technique to be a valuable new tool for dynamic ECG auxiliary diagnosis.
