The parameters of various morphologies of ECG waveform are basic in charact
erizing them as normal or otherwise. The use of multiscale analysis, throug
h biorthogonal wavelets presented in this paper, appears very promising for
such a characterization. This is on account of the fact that various morph
ologies are excited better at different scales. From these different scales
, amplitudes, durations and various segments, widths can be determined more
accurately. Simulation studies, with real ECG data, have shown that even w
hen the signal-to-noise ratios are poor, the proposed technique can be used
to accurately estimate the said parameters. (C) 1999 IPEM. Published by El
