Key result
KNN classifier with Burg method showed good results at model order 9, and PCA classifier with Yule-Walker method showed good results at model order 8 for ECG signal interpretation.
KNN with Burg method and PCA with Yule-Walker method are effective for classifying ECG signals of atrial arrhythmias.

Should not change ECG interpretation practices; leaves open optimized autoregressive modeling for atrial arrhythmia classification.
Gupta et al. (2018) studied Atrial Tachycardia, Premature Atrial Contractions and Sinus Arrhythmia (n=3). KNN and PCA classifiers with Autoregressive modelling was evaluated on Classification performance and Signal to Noise ratio (SNR). KNN classifier with Burg method showed good results at model order 9, and PCA classifier with Yule-Walker method showed good results at model order 8 for ECG signal interpretation.
