An Approach of QRS Detection Using Fractional Order Digital Differentiators | Chapter 15 | Highlights on Medicine and Medical Science Vol. 16

The detection of the QRS complex is a key step in heart rate variability analysis. It has been demonstrated that methods based on differentiation are efficient and thus suitable for real-time analysis. Simultaneously, fractional order digital differentiators are gaining popularity in a variety of fields of study. The proposed transfer functions of digital differentiators are used in this research to attempt to detect QRS complexes. The Continued Fraction Expansion Method is used to obtain the transfer functions in the s domain. For discretization, the Bilinear Transform and the AlAlaoui Transform are used. QRS complexes are detected with the help of these filters. The outcome has been shown to be comparable to traditional methods.
