Hybrid CNN-LSTM model for ECG-based arrhythmia detection in internet of medical things

Electrocardiogram (ECG) signals play a crucial role in the internet of medical things (IoMT) by enabling real-time heart health assessment, particularly for cardiovascular disease monitoring and personalized health management in sports and fitness applications. This study proposes a hybrid deep learning model that integrates a long short-term memory (LSTM) network and a convolutional neural network (CNN) to enhance ECG signal classification. The LSTM network captures the temporal dependencies of ECG sequences, while the CNN extracts localized spatial features, allowing for a comprehensive analysis of heart rhythms. By utilizing preprocessed ECG data as input, our model effectively combines feature extraction and classification into a unified framework. We evaluate the proposed approach using a publicly available datase. Experimental results demonstrate that our method achieves high accuracy in distinguishing various heart rhythm patterns, offering a promising solution for automated arrhythmia detection in IoMT applications.
