QRS detection algorithm based on the quadratic filter
QRS detection algorithm with noise removal method based on the quadratic filter. Results show the significant improvement in QRS signal to noise ratio. Use only a single fixed threshold without additional post processing techniques. Evaluate the algorithm with 109,483 beats of QRS complexes from MIT-BIH database. Achieve overall sensitivity 99.82% and positive predictive rate 99.81%.
