Abstract
Wavelet transformation based on multiresolution decomposition using the method proposed by Mallat (1989) was applied to the signal-averaged ECG (SAECG) of postinfarction patients with left (76), right (79) and no (195) bundle branch block (BBB) in order to discriminate and characterize spectrally these groups. The relative energy of the QRS complex was calculated in seven frequency bands ranging from 0 to 250 Hz. Left BBB patients had a significant energy reduction (p
