A Wavelet Transform Based Multichannel Detection Of Ventricular Late Potentials

In this paper, a wavelet transform (WT) based multichannel detection system was proposed and applied to the detection of ventricular late potentials (VLPs). Preliminary results showed that the system is capable of detecting every-beat surface VLPs by a weighted averaging technique in the Wand In-transformed domain. Also, we have shown that WT is insensitive to the precise shape of the signal waveform by a robust theorem.
