Complete Ensemble Emd And Hilbert Transform For Heart Beat Detection
VI LATIN AMERICAN CONGRESS ON BIOMEDICAL ENGINEERING (CLAIB 2014)(2014)
摘要
The problem of heart beat detection is addressed with a new noise-assisted Empirical Mode Decomposition (EMD) method. Although existing algorithms show very good performances in good conditions, they have some difficulties in the presence of complicated waveforms, high levels of noise and strong baseline drift. Here we present a fully automated and unsupervised algorithm. Hilbert transform is used for the construction of envelopes of the extracted components and an entropy-like criterion is used for mode selection. The more difficult electrocardiogram (ECG) derivations are used in this work and the results are compared with the algorithm of Afonso et al., showing a better performance for our algorithm.
