This work aims to improve the detection accuracy of QRS complexes in ECG signals using mathematical morphology.
Implemented a peak-valley extractor using a simple morphological operator and a horizontal line segment as a structuring element.
Assessed the approach's accuracy using a standard ECG library.
Measured sensitivity and positive predictivity to evaluate performance.
Achieved a sensitivity of 99.38% and a positive predictivity of 99.48% for the QRS complex detection.
