Subband analysis of cardiac late potentials

Subband analysis of cardiac late potentials

A set of Gaussian wavelet filters were used to decompose the averaged EC G into three frequency bands. Four subaverages from the leads X, Y and Z were filtered. The endpoint of beat related activity in each lead and frequency band were determined by using ensemble correlation on the four subaverages...

description A set of Gaussian wavelet filters were used to decompose the averaged EC G into three frequency bands. Four subaverages from the leads X, Y and Z were filtered. The endpoint of beat related activity in each lead and frequency band were determined by using ensemble correlation on the four subaverages. Endpoints of QRS-related activity as obtained from the subband filtered data were compared to those of highpass filtered data.
