摘要：
This paper describes a new method for automatic detection of obstructive sleep apnea (OSA) based on artificial neural networks (ANN) using regular electrocardiogram (ECG) recordings. ECG signals were pre-processed and segmented to extract the P-waves; then three P-wave features were extracted: the P-wave duration (T (p) ), the P-wave dispersion (P (d) ), and the time interval from the peak of the P-wave to the R-wave (T (pr) ). Combinations of the three features were used as features for classification using ANN. For each feature combination studied, 70% of the input data was used for training the ANN, 15% for validating, and 15% for testing the results. Perfect agreement between expert's scores and the ANN scores was achieved when the ANN was applied on T (p) , P (d) , and T (pr) taken together, while substantial agreements were achieved when applying the ANN on the feature combinations T (p) and P (d) , and T (p) and T (pr) .
