This paper presents an efficient infinite impulse response type digital fractional order differentiator (DFOD) based electrocardiogram (ECG) pre-processor to detect QRS complexes. First, an efficient optimizer namely, Antlion optimization algorithm is employed to solve the proposed DFOD design problem. Then, the designed DFOD is deployed in the pre-processing stage of a threshold independent R-peak detection technique. Finally, the proposed QRS complex detector is thoroughly assessed on the… CONTINUE READING

Key Quantitative Results

  • The overall sensitivity of 99.89% and positive predictivity of 99.88% are incurred by considering all the six databases.
  • Furthermore, the proposed design has made a considerable performance improvement over the existing state-of-the-art DFODs as portrayed in Table V, and hence, the proposed design has incurred an average percentage improvement of 70% with respect to the reported third order DFODs.
  • The overall sensitivity, positive predictivity, and detection error rate of 99.89%, 99.88%, and 0.24% are obtained from the proposed QRS detector which outperforms all the earlier reported QRS detectors.
