This study introduces an interpretable shapelet-based method using dynamic and deep learning for accurate myocardial infarction (MI) detection from ECG signals, achieving high diagnostic performance.

Area of Science:

Cardiology
Biomedical Engineering
Artificial Intelligence in Medicine

Background:

Myocardial infarction (MI) is a leading cause of global mortality.
Electrocardiography (ECG) is vital for MI diagnosis but faces challenges due to subtle signal changes.
Accurate and timely MI detection is critical for reducing fatality rates.

Purpose of the Study:

To develop an interpretable shapelet-based approach for enhanced MI detection using ECG.
To improve the accuracy of MI diagnosis by extracting discriminative features from ECG dynamics.
To leverage dynamic learning and deep learning for robust MI identification.

Main Methods:

Utilized dynamic learning to capture intrinsic ECG signal dynamics.
Employed a deep neural network to extract and select MI-specific shapelets from ECG dynamics.

Keywords:

deep learning dynamic learning ensemble model myocardial infarction shapelets
