Does a modified adaptive threshold method accurately detect QRS complexes in ECG signals?
A modified adaptive threshold method based on statistical analysis demonstrates high sensitivity and positive predictivity for QRS complex detection in ECG signals.
Hussein et al. (2019) studied Arrhythmia (n=48). Modified adaptive threshold algorithm vs. State-of-the-art QRS detection algorithms was evaluated on QRS complex detection sensitivity. The modified adaptive threshold algorithm achieved high QRS complex detection performance with a sensitivity of 99.62% and a positive predictivity of 99.88% on the MIT-BIH arrhythmia database.
