ECG Congestive Heart Failure Detection in Python Projects
Abstract
Congestive Heart Failure (CHF) is a severe cardiovascular condition that can lead to critical complications if not diagnosed early. Electrocardiogram (ECG) signals provide vital information about the heart’s electrical activity, enabling non-invasive detection of CHF. The project ECG-Based Congestive Heart Failure Detection in Python Projects focuses on developing an intelligent system to automatically identify CHF using ECG signals. Python is used as the development platform due to its robust libraries for signal processing, machine learning, and deep learning, including NumPy, SciPy, Pandas, TensorFlow, Keras, and Matplotlib. The system preprocesses ECG signals to remove noise, extracts relevant features, and applies machine learning and deep learning models such as Support Vector Machines (SVM), Random Forest, Convolutional Neural Networks (CNN), and Long Short-Term Memory (LSTM) networks to detect CHF. This automated approach facilitates early diagnosis, reduces manual workload, and improves patient care and monitoring.

Existing System

Existing CHF detection methods primarily rely on clinical examination, echocardiography, and manual analysis of ECG signals by cardiologists. While effective, these methods are time-consuming, require specialized expertise, and may suffer from human error, especially with large-scale screening. Traditional computer-aided diagnostic systems use hand-crafted features extracted from ECG signals combined with classical machine learning models such as k-NN, SVM, or Decision Trees. However, these approaches often lack robustness against noisy data, fail to capture temporal dependencies in ECG signals, and cannot scale efficiently to handle continuous patient monitoring. Consequently, early detection of CHF is limited in speed, accuracy, and scalability.

Proposed System

The proposed system introduces a Python-based automated framework for CHF detection using ECG signals. ECG data is preprocessed through noise removal, baseline correction, normalization, and segmentation into heartbeats or time windows. Feature extraction techniques, such as time-domain, frequency-domain, and wavelet-based features, are applied to highlight relevant signal characteristics. Deep learning models like CNNs are used to automatically learn spatial features, while LSTM networks capture temporal dependencies and sequential patterns in ECG signals. Hybrid models combining CNN-LSTM can further improve classification accuracy. The system is trained and validated on publicly available ECG datasets such as the MIT-BIH CHF Database. Performance evaluation metrics include accuracy, precision, recall, F1-score, and ROC-AUC. The proposed approach enables fast, reliable, and scalable detection of CHF, providing clinicians with valuable decision support and enabling proactive interventions to prevent severe cardiac events.
