This research aims to develop and validate a real-time algorithm for detecting QRS complexes in ECG signals.
Developed an algorithm utilizing digital analyses of slope, amplitude, and width for QRS detection.
Implemented a digital bandpass filter to reduce false detections from interference.
The algorithm adapts detection thresholds and parameters based on changes in QRS morphology and heart rate.
Achieved a detection accuracy of 99.3% for QRS complexes on the MIT/BIH arrhythmia database.
