ECG signal recordings are used to diagnose various heart conditions. Diagnosis of heart abnormalities in ECG signal recordings is done by classifying the heartbeat rhythm into 5 classes, namely non ectopic beat (N), supraventricular ectopic beats (S), ventricular ectopic beats (V), fusion beat (F) and unknown beat (Q). This research will combine the preprocessing stage using Stationary Wavelet Transform (SWT) for signal quality improvement and beat classification of ECG signals in the MIT-BIH Arrhythmia Database using a combination of DenseNet and LSTM architectures. DenseNet is used to capture features from ECG signals through direct connection between layers and LSTM is used to filter features from DenseNet according to data order through gated mechanisms. The SWT method obtained an average SNR value of 26.65 dB, indicating good signal quality with low noise. Model performance evaluation was conducted by measuring accuracy, sensitivity, specificity, precision and F1-score. The results of the performance evaluation obtained an average accuracy of 98.07%, indicating that the model can classify almost all data correctly. The average sensitivity of 95.15% shows that the model can group data that is a certain class correctly. The average specificity of 98.78% shows that the model can group data that is not a certain class correctly. The average precision of 95.17% indicates the model has excellent accuracy in predicting each class. The average F1-score of 95.1% indicates the model is very good at maintaining balance in distinguishing each class, both the class and those that do not belong to the class. The results per class in classes F, S, V, and Q were excellent in all performance evaluation metrics at more than 90%. In class N, the accuracy, specificity, and precision values were very good at more than 90%, but the sensitivity and F1-score were less than 90%. Based on this study, the proposed model provides excellent results overall, but development is needed to distinguish between normal and arrhythmic beats, as well as improvements to the architecture to increase the sensitivity and F1-score values in class N which are less than 90%.
