Pe. Trahanias, AN APPROACH TO QRS COMPLEX DETECTION USING MATHEMATICAL MORPHOLOGY, IEEE transactions on biomedical engineering, 40(2), 1993, pp. 201-205
An approach to QRS complex detection based on mathematical morphology
is presented in this communication. QRS complexes are detected by the
application of a simple morphological operator. This operator works as
a peak-valley extractor and it is controlled by the shape of the stru
cturing element. A set (horizontal line segment) is used as structurin
g element resulting in very fast execution times. The accuracy of this
approach has been tested using a standard ECG library; a sensitivity
of 99.38% and a positive predictivity of 99.48% have been achieved.
