I’ve made the Pattern Recognition Letters paper, which was largely derived from work that I did for my Master’s thesis, available online. The reference is:
Froese, T., Hadjiloucas, S., Galvao, R.K.H., Becerra, V.M. & Coelho, C.J. (2006), “Comparison of extrasystolic ECG signal classifiers using Discrete Wavelet Transforms”, Pattern Recognition Letters, 27(5), pp. 393-407
It can be downloaded from here.
