Yh. Hu et al., APPLICATIONS OF ARTIFICIAL NEURAL NETWORKS FOR ECG SIGNAL-DETECTION AND CLASSIFICATION, Journal of electrocardiology, 26, 1993, pp. 66-73
The authors have investigated potential applications of artificial neu
ral networks for electrocardiographic QRS detection and beat classific
ation. For the task of QRS detection, the authors used an adaptive mul
tilayer perception structure to model the nonlinear background noise s
o as to enhance the QRS complex. This provided more reliable detection
of QRS complexes even in a noisy environment. For electrochardiograph
ic QRS complex pattern classification, an artificial neural network ad
aptive multilayer perception was used as a pattern classifier to disti
nguish between normal and abnormal beat patterns, as well as to classi
fy 12 different abnormal beat morphologies. Preliminary results using
the MIT/BIH (Massachusetts Institute of Technology/Beth Israel Hospita
l, Cambridge, MA) arrhythmia database are encouraging.
