A novel method is proposed in this paper for the feature extraction of electrocardiogram (ECG). The shape characteristic of the QRS complex has been a diagnostic criterion of cardiac arrhythmia. In other words, geometric property of the QRS complex is a very important kind of feature. Different with other feature extraction algorithms, the proposed method utilizes geometric algebra (GA) to extract...
A novel method is proposed in this paper for the feature extraction of electrocardiogram (ECG). Different with other algorithms, the proposed method utilizes independent component analysis (ICA) and wavelet transform to get an ensemble feature composed of ICA-based features and the QRS complex width feature. The QRS complex is the most characteristic waveform of an ECG signal and its width has been...
