Abstract :
The wavelet transform of an ECG with a complex Gabor filter can be changed to two representations where the real and imaginary part are combined in a nonlinear way to an energy signal and a phase signal. The energy signal is used to detect and localize P waves, whereas the phase signal is used to classify the P waves as monophasic, M-shaped or biphasic
