Project Overview
The project focused on developing an AI-powered clinical decision support system to enhance the detection and classification of cardiac arrhythmias from ECG signals. The system automates the analysis of extensive ECG data, addressing the challenges of time-consuming manual reviews, human error, and delayed diagnoses.
Performance Summary
The system significantly improved the efficiency and accuracy of arrhythmia detection. Key performance highlights include:
- Reduced Analysis Time: The system decreased the time required for reviewing ECG reports by up to 50%, acting as a reliable “second opinion” and allowing clinicians to focus on complex cases and patient interactions.
- High Accuracy: Achieved an overall accuracy of over 95% on standard databases and real-world clinical data.
- Clinical Metrics:
- Sensitivity (Recall): 98%, ensuring a high rate of correctly identifying patients with arrhythmias (True Positive Rate), minimizing missed cases.
- Specificity: 97%, accurately identifying healthy individuals (True Negative Rate), reducing false positives.
- Positive Predictive Value (PPV): 94%, indicating a high likelihood that a positive result reflects a true arrhythmia case.
- Negative Predictive Value (NPV): 99%, confirming the reliability of negative results in identifying healthy individuals.
Trends and Improvements
The system’s implementation marked a transformative step in clinical diagnostics by streamlining workflows and enhancing diagnostic precision. By automating the identification of suspicious ECG segments, it reduced clinician workload and accelerated early detection, leading to improved patient outcomes and lower healthcare costs. The use of advanced preprocessing, deep learning models, and NLP-based report analysis ensured robust performance across diverse datasets. Continuous refinement and integration with real-world clinical data further strengthened the system’s reliability and applicability.
This project demonstrates a strategic advancement in leveraging AI to address critical healthcare challenges, delivering measurable improvements in efficiency, accuracy, and patient care quality.
