Advanced signal processing techniques are critical in the early
detection and classification of cardiac abnormalities. This study
addresses the challenge of detecting QRS-complexes and classifying
arrhythmias in embedded systems. Traditional methods often struggle
with high false detection rates and computational inefficiencies. Our
approach leverages Long Short-Term Memory (LSTM) networks to
enhance detection accuracy and classification performance by
integrating hybridized features from electrocardiogram (ECG) signals.
We propose a novel framework that combines time-domain features
with frequency-domain characteristics, optimizing signal
preprocessing and feature extraction. The LSTM model was trained on
a dataset of 10,000 ECG records, achieving a QRS detection accuracy
of 98.5% and an arrhythmia classification accuracy of 95.3%. Our
embedded system implementation demonstrates real-time processing
capabilities with a latency of 32 milliseconds per signal. The results
indicate substantial improvements in both detection precision and
classification reliability, making our system a robust solution for
embedded cardiac monitoring applications.
