Key result
Chaos theory applied to QRS features achieves ~100% arrhythmia detection accuracy using Decision Tree.
Why the study?
Classifications using combined raw ECG, patient experience, and QRS feature selection methods with machine learning algorithms have not been examined before for arrhythmia detection.
Does the application of chaos theory to QRS features combined with clinical data improve the accuracy of machine learning algorithms in detecting arrhythmias from ECG signals?

Absolute Event Rate: 99.8% vs 94%
Applying chaos theory to QRS features combined with clinical data significantly improves machine learning classification accuracy for arrhythmia detection up to 99.8%.
Should not yet change ECG interpretation practice; leaves open prospective validation of chaos-enhanced ML models.
Heart monitoring improves life quality. Electrocardiograms (ECGs or EKGs) detect heart irregularities. Machine learning algorithms can create a few ECG diagnosis processing methods. The first method uses raw ECG and time-series data. The second method classifies the ECG by patient experience. The third technique translates ECG impulses into Q waves, R waves and S waves (QRS) features using richer information. Because ECG signals vary naturally between humans and activities, we will combine the three feature selection methods to improve classification accuracy and diagnosis. Classifications using all three approaches have not been examined till now. Several researchers found that Machine Learning (ML) techniques can improve ECG classification. This study will compare popular machine learning techniques to evaluate ECG features. Four algorithms—Support Vector Machine (SVM), Decision Tree, Naive Bayes, and Neural Network—compare categorization results. SVM plus prior knowledge has the highest accuracy (99%) of the four ML methods. QRS characteristics failed to identify signals without chaos theory. With 99.8% classification accuracy, the Decision Tree technique outperformed all previous experiments.

Aboghazalah et al. (2024) studied Cardiac Arrhythmia (n=590). Chaos theory applied to QRS features combined with clinical data vs. Raw ECG signals and other feature combinations without chaos theory was evaluated on Classification accuracy. Applying chaos theory to QRS features combined with clinical data achieved a 99.8% classification accuracy for arrhythmia detection using a Decision Tree algorithm.
