Introduction: Cardiovascular diseases continue to be one of the leading causes of mortality worldwide, making early detection crucial for reducing complications and fatalities. Traditional diagnostic methods often depend on the manual interpretation of cardiac signals, which can be time-consuming and reliant on the expertise of clinicians. However, advances in deep learning and data mining have facilitated the automated analysis of medical signals and the detection of hidden patterns. This study presents a novel approach to identifying cardiac diseases based on ECG signals. Method: In this study, we developed a hybrid deep learning model that utilizes the fast version of the YOLO network to extract mid-level features from ECG signals, combined with the XGBoost algorithm to improve classification performance. ECG signals from the MIT-BIH Arrhythmia Database were first extracted and preprocessed. These signals were then input into the YOLO network to generate feature vectors. The outputs of the network were subsequently fed into the XGBoost algorithm for final classification using an ensemble of multiple weak decision trees. Finally, we compared the proposed model with established conventional methods. Results: The results demonstrated that the YOLO network effectively extracts key features from ECG signals, and its integration with XGBoost significantly enhances overall model accuracy. The proposed model outperformed baseline methods, including simple neural networks and support vector machines (SVMs). Evaluation on the MIT-BIH Arrhythmia Database revealed substantial improvements in classification accuracy, as well as enhanced sensitivity and specificity. These findings indicate that combining deep learning with boosting algorithms provides an efficient approach for medical signal analysis. Conclusion: The YOLO-XGBoost hybrid model offers an accurate and innovative approach for detecting cardiac diseases from ECG signals. In addition to enhancing classification accuracy, this method is well-suited for implementation in clinical decision support systems and can serve as an efficient tool for patient screening. Future work could involve validating the model with larger and more diverse datasets and integrating it into intelligent medical systems.
