Key result
AI-based IIR filter improves QRS peak detection and classification accuracy ~13% vs Pan-Tompkins.
Why the study?
Accurate interpretation and acquisition of the QRS complex and R wave are vital for analyzing cardiac rhythm irregularities and HRV, requiring effective elimination of baseline wandering and power line interference.
Effect estimate: 13% increase over Pan-Tompkins, 8% increase over FIR-filter
A novel AI-based reduced order IIR filter improves the accuracy of ECG QRS peak detection and arrhythmia classification compared to standard methods.

Amhia et al. (2021) studied Arrhythmia. Reduced order IIR filter with min-max optimization vs. Basic Pan-Tompkins method and existing FIR-filter-based classification rules was evaluated on Accuracy of QRS peak detection and classification (13% increase over Pan-Tompkins, 8% increase over FIR-filter). A new artificial-intelligence-based approach using a reduced order IIR filter increased QRS peak detection and classification accuracy by around 13% over the basic Pan-Tompkins method.
