Optimización en el Desempeño de Algoritmos de Detección de Complejos QRS

This document presents the implementation and the per formance evaluation of several algor ithms proposed for the detection of QRS complexes. Also, the optimization of the algor ithms is made maximizing the per formance measures of sensitivity and precision. An special emphasis is made for an hybr id algor ithm based on linear filter ing, Hilber t tr ansform and adaptive threshold; the per formance of this algor ithm is compared with respect to other s based on the amplitude and der ivatives of the signal, also it is compared with other method based on wavelet tr ansform. The tests are per formed with the standard databases MIT­Arrhythmia and European ST­T in order to evaluate the results obtained from the implemented methods in this document with respect to the results obtained with other proposed methods. As a result, the algor ithms based on wavelet tr ansform, digital filter s and hybr id are the methods that show the best per formance.
