Insights
This study introduces a deep learning method for recognizing premature ventricular contractions (PVCs), a common heart arrhythmia. The approach uses electrocardiogram (ECG) signal features to improve automatic heart disease diagnosis.
Area of Science:
- Cardiology
- Biomedical Engineering
- Artificial Intelligence
Background:
- Electrocardiogram (ECG) signals are crucial for diagnosing heart diseases, with abnormal heartbeats like premature ventricular contractions (PVCs) indicating serious conditions.
- Automated computer-assisted techniques are increasingly vital for reducing the diagnostic burden of identifying heart arrhythmias.
- PVCs are a common arrhythmia originating in the heart's lower chambers, potentially leading to severe health issues.
Purpose of the Study:
- To propose and evaluate a deep learning-based approach for accurate recognition of premature ventricular contractions (PVCs).
- To leverage extracted ECG signal features for enhanced automatic arrhythmia detection.
Main Methods:
- Extracted 10 heartbeat and statistical features, including morphological (RS amplitude, QR amplitude, QRS width) and statistical measures, from 20-second ECG signal segments.
- Constructed feature vectors from the extracted ECG data.
- Utilized a convolutional neural network (CNN) to analyze feature patterns for effective PVC classification.

Abstract:
Electrocardiogram signal (ECG) is considered a significant biological signal employed to diagnose heart diseases. An ECG signal allows the demonstration of the cyclical contraction and relaxation of human heart muscles. This signal is a primary and noninvasive tool employed to recognize the actual life threat related to the heart. Abnormal ECG heartbeat and arrhythmia are the possible symptoms of severe heart diseases that can lead to death. Premature ventricular contraction (PVC) is one of the most common arrhythmias which begins from the lower chamber of the heart and can cause cardiac arrest, palpitation, and other symptoms affecting all activities of a patient. Nowadays, computer-assisted techniques reduce doctors' burden to assess heart arrhythmia and heart disease automatically. In this study, we propose a PVC recognition based on a deep learning approach using the MIT-BIH arrhythmia database. Firstly, 10 heartbeat and statistical features including three morphological features (RS amplitude, QR amplitude, and QRS width) and seven statistical features are computed for each signal. The extraction process of these features is conducted for 20 s of ECG data that create a feature vector. Next, these features are fed into a convolutional neural network (CNN) to find unique patterns and classify them more effectively. The obtained results prove that our pipeline improves the diagnosis performance more effectively.
