Abstract

Cardiovascular diseases (CVDs) are one of the leading causes of mortality worldwide, creating a growing demand for accurate and real-time cardiac monitoring systems. Electrocardiogram (ECG) signals are widely used to monitor the electrical activity of the heart and assist in the diagnosis of various cardiac abnormalities such as arrhythmias, myocardial infarction, and ischemic heart diseases. However, ECG signals are often affected by different types of noise including baseline wander, power line interference, motion artifacts, and muscle noise, which can reduce diagnostic accuracy. This project proposes an automated heart disease diagnosis system based on Digital Signal Processing (DSP) techniques for effective ECG signal analysis and interpretation. The system acquires real-time ECG data and applies preprocessing techniques such as digital filtering to remove noise and improve signal quality. The Pan–Tompkins algorithm is utilized for accurate detection of the QRS complex and extraction of important ECG parameters including PR interval, QT interval, ST segment, and R–R interval. The proposed system further integrates machine learning techniques for automatic classification and detection of cardiac abnormalities. By analyzing extracted ECG features, the system can identify arrhythmias and other heart-related disorders with improved accuracy and reliability. The processed data and diagnostic results are displayed in real time, enabling continuous patient monitoring and assisting healthcare professionals in early diagnosis. In addition, the system supports IoT-based remote healthcare monitoring, allowing doctors to access patient information remotely for timely medical intervention. The developed solution is cost-effective, portable, and suitable for real-time applications, making it beneficial for hospitals, clinics, and home-based healthcare systems. Experimental analysis demonstrates that the combination of DSP techniques and intelligent classification methods significantly enhances ECG signal interpretation and reduces diagnostic errors, thereby improving overall patient care and treatment outcomes.

Full Article/Conclusion

The proposed system for the Digital Signal Processing of ECG signals offers a highly reliable and automated solution for the diagnosis of heart diseases. By effectively implementing digital filters and feature extraction algorithms on an embedded platform, the system successfully cleans raw ECG data and identifies critical cardiac abnormalities in real-time. The integration of IoT capabilities allows for continuous remote patient monitoring, significantly reducing the burden on healthcare facilities and minimizing the risk of delayed treatment. While severe motion artifacts from patient movement remain a challenge requiring advanced adaptive filtering, the system demonstrates immense potential for modern telehealth. Future enhancements could include the deployment of deep learning models (such as CNNs) directly onto edge devices for even higher classification accuracy across a broader spectrum of cardiovascular diseases.
