Key result
A convolutional neural network achieved an F1 score of 83% on the test set for classifying short ECG segments, compared to 79% for a state-of-the-art feature-based classifier.
Why the study?
Does a Convolutional Neural Network improve the F1-score for detecting arrhythmia from short ECG segments compared to a feature-based classifier?
Does a Convolutional Neural Network improve the F1-score for detecting arrhythmia from short ECG segments compared to a feature-based classifier?
Deep learning algorithms using ResNet architectures can effectively classify short ECG recordings into normal and arrhythmic classes without requiring hand-engineered features, outperforming traditional feature-based classifiers.

Andreotti et al. (2017) studied Arrhythmia (Atrial Fibrillation) (n=12,186). Convolutional Neural Network (ResNet) vs. Feature-based classifier was evaluated on F1 score for classifying ECG segments into four classes (AF, normal, other, noise) on the hidden test set. A convolutional neural network achieved an F1 score of 83% on the test set for classifying short ECG segments, compared to 79% for a state-of-the-art feature-based classifier.
