A Robust Method for Detecting the QRS Complex of the ECG Signal

Resumo

This work was devoted to a robust method for detection of the QRS complex of the ECG signal based on the application of a band-pass filter with a linear phase characteristic, the Hilbert transform, and an adaptive threshold- ing algorithm. The efficiency of various QRS complex detectors in the presence of pronounced artifacts was studied. The efficiency of the suggested method was verified using different ECG records available from the MIT PhysioNet open access database.
