Key result
CNN-LSTM deep learning model detects ECG arrhythmias with ~99% accuracy.
Why the study?
Deep learning methods have shown promise in healthcare prediction challenges involving ECG data, motivating their application to classify arrhythmia using publicly available datasets.
Deep learning models, particularly CNN combined with LSTM and attention mechanisms, can classify ECG arrhythmias with over 99% accuracy.
Deep learning ECG arrhythmia models show research promise; prospective clinical validation needed before any practice consideration.
The electrocardiogram (ECG) is one of the most widely used diagnostic instruments in medicine and healthcare. Deep learning methods have shown promise in healthcare prediction challenges involving ECG data. This paper aims to apply deep learning techniques on the publicly available dataset to classify arrhythmia. We have used two kinds of the dataset in our research paper. One dataset is the MIT-BIH arrhythmia database, with a sampling frequency of 125 Hz with 1,09,446 ECG beats. The classes included in this first dataset are N, S, V, F, and Q. The second database is PTB Diagnostic ECG Database. The second database has two classes. The techniques used in these two datasets are the CNN model, CNN + LSTM, and CNN + LSTM + Attention Model. 80% of the data is used for the training, and the remaining 20% is used for testing. The result achieved by using these three techniques shows the accuracy of 99.12% for the CNN model, 99.3% for CNN + LSTM, and 99.29% for CNN + LSTM + Attention Model.
